Run File::Find::find with no_chdir=>1 
Without no_chdir=>1 the unshared child process in unshare mode needs
read permissions for the directory from which mmdebstrap is executed.
With this change, the current working directory does not need to be
world-readable anymore.

Use apt patters to select priority variants 
- requires apt >= 2.3.10
 - we can drop having to run apt-get indextargets and parse Packages
   files ourselves
 - we can drop the layer violation that computed the package set in
   run_download() and passed the package set around in setup() to
   run_install()
 - packages are selected by suite unless the suite is the empty string

c61e81a244 Relax dpkg version regex 
For non-release builds the version will include the number of commits since last release and the commit hash with dashes, e.g. 1.20.8-46-g0881.
For downstream distros it seems it may include their identification strings, e.g. 1.20.9ubuntu2.

Make the regex match everything after the version number to avoid incorrectly erroring on such versions.

use rm and find instead of remove_tree() 
* remove_tree() requires the CWD to be accessible or fails with
   cannot chdir to $CWD from $DIR_TO_DELETE: Permission denied, aborting.
 * CWD is not always accessible -- example: run mmdebstrap from a
   directory only accessible by the current user (like a tempdir) in
   unshare mode
 * find from findutils *also* requires CWD to be accessible but it's
   easier to temporarily change CWD in a subprocess because using
   there is no utility in perl core that changes CWD temporarily and
   cleans up after itself
 * we need to use find from findutils instead of rm in unshare mode
   because the root directory itself might not be removable by the
   unshared user so we only want to remove its subdirectories

Pass extended attributes (excluding system) to tar2sqfs 
/bin/ping (from iputils-ping) uses the security capabilities to allow
users to use the program:

```
$ getcap /bin/ping
/bin/ping cap_net_raw=ep
```

Debian testing/unstable images (variant important) contain security and
system attributes:

```
$ mmdebstrap --variant=important bullseye root.tar
$ tar --xattrs --xattrs-include='*' -vv -tf root.tar | grep -B 1 '^ '
-rwxr-xr-x* 0/0           77432 2021-02-02 18:49 ./bin/ping
  x: 20 security.capability
--
drwxr-sr-x* 0/102             0 2021-05-07 15:10 ./var/log/journal/
  x: 44 system.posix_acl_access
  x: 44 system.posix_acl_default
```

When generating a squashfs image with mmdebstrap 0.7.5-2, these security
capabilities are lost. Example for building a squashfs image in a
minimal Debian unstable schroot:

```
$ apt install -y mmdebstrap squashfs-tools-ng
$ mmdebstrap --variant=important buster root.squashfs
$ rdsquashfs -x /bin/ping root.squashfs
$
```

tar2sqfs from squashfs-tools-ng 1.0.4-1 supports encoding extended
attributes from the namespace `user`, `trusted`, and `security` (see
`include/sqfs/xattr.h`). GNU tar (version 1.34) supports these three
namespaces plus the namespace `system`.

Passing extended attributes from the `system` namespace to tar2sqfs will
produce an error:

```
ERROR: squashfs does not support xattr prefix of system.posix_acl_default
```

So pass the extended attributes to tar2sqfs, but exclude the `system`
namespace. Then ping will keep its security attributes:

```
$ rdsquashfs -x /bin/ping root.squashfs
security.capability=0x0100000200200000000000000000000000000000
```
