Switch variant apt from 'apt-get dist-upgrade' to apt patterns 
The dist-upgrade method will fail to install essential packages but
still exit successfully without reporting an error, see #1072218

add flock on temporary directory in /tmp 
Since systemd 256~rc3-3, /tmp is regularly cleaned up, removing files
older than 10 days. Since a rootfs contains files with timestamps
potentially much older than that, we exclude our temporary directory by
adding an exclusive lock on it which will stop systemd-tmpfiles from
cleaning up anything in it.

Thanks: Peter Pentchev <roam@ringlet.net>

In unshare mode, make all mounts private recursively 
This emulates what unshare(1) does by default or by passing
--propagation=private explicitly. Mounting and unmounting filesystems
will affect mounts outside the namespace which are marked as shared (see
last column of `findmnt -o+PROPAGATION`). Since mmdebstrap's goal is to
isolate the mounts in the new namespace, we perform the equivalent of

    mount(NULL, "/", MS_REC | MS_PRIVATE, NULL);

from util-linux/sys-utils/unshare.c:set_propagation() which is in shell:

    mount --make-rprivate /

See mount_namespaces(7) for details. Without setting this, unmounting
/sys (and its sub-mounts) in unshare mode as root user will also unmount
the sub-mounts of /sys on the outside of the namespace. This breaks
tests/unshare-as-root-user which will fail to shut down with the following
errors in the log:

[FAILED] Failed unmounting mnt.mount - /mnt.
[FAILED] Failed unmounting run-lock.mount - Legacy Locks Directory /run/lock.
[...]
[  OK  ] Reached target poweroff.target - System Power Off.

Afterwards it will stall indefinitely. Stopping mmdebstrap from messing
with the /sys mounts on the outside stops this behaviour and allows to
cleanly shut down the virtual machine.

Thanks: Helmut Grohne

fd33bd2a40 set DPkg::Chroot-Directory in APT_CONFIG 
This is so that users calling apt-get install from a hook only need to
have APT_CONFIG=$MMDEBSTRAP_APT_CONFIG set and do not also have to pass
-oDPkg::Chroot-Directory="$1".

This breaks users running apt-get with
DPkg::Options::=--force-script-chrootless or with Dpkg::Pre-Install-Pkgs
from within a hook with APT_CONFIG=$MMDEBSTRAP_APT_CONFIG.

In those situations, DPkg::Chroot-Directory has to be set to the empty
string explicitly with -o to overwrite the APT_CONFIG setting.
