As long as you can make it so that the same path to the deb file works
inside and outside of the chroot using file:// as a mirror is no longer
a problem with the previous work.
Guessing filenames is boring. What if we could ask apt to tell us which
debs it downloaded (or found lying around elsewhere) directly? Turns out
we can rather easily avoiding a bunch of guesswork.
EIPP stands for "External Installation Planner Protocol" and is rather
similar to EDSP but with the clear advantage that we can extract the
information we need more easily as we can tell apt to write the file for
us rather than playing solver-in-the-middle and the problem space is
much smaller meaning less data for apt to generate and to pass through
our hands.
The idea here is simply that every package which doesn't have a Status
field in EIPP has the uninstalled status and the only reason its is part
of the EIPP request is that we want to change this by installing it.
That could be verified via the Install header at the start of the
request, but this commit doesn't implement that.
Note that this means we need "more" than the download-only mode can
provide: Either a simulation or "the real deal". Except we modify the
later to be a fancy no op.
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.
These lines are copied from the "Debian desktop on USB stick" example.
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
