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.

The generated image will not be bootable if `mbr.bin` is not installed
into the MBR.

don't bother with /sbin/start-stop-daemon and /usr/sbin/policy-rc.d
if they're not a regular files (e.g. symlinks)

- 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
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.
Fixes#18
* 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
There are now systems with 160 cores (debci runs on two Ampere Altra
ARMv8 Neoverse-N1), which makes xz fail with: "xz: (stdin): Cannot
allocate memory"
- use /etc/ld.so.conf from the chroot instead of the host
- parse /etc/ld.so.conf instead of blindly accessing /etc/ld.so.conf.d
- add libraries from the chroot instead of the host
