Minimize the number of manually installed packages in images by marking
dependencies of metapackages as automatically installed.
Squashed commits:
* minimize-manual.py: Followup with some cleanup, correct permissions
* fixup: Do not assume current directory
* Reorganize minimal-manual file location.
Test showed very little difference in file-size between -0 and -9 while
both compression and decompression need much less memory and compression
needs less CPU time for -0.
Supported xz versions before 5.2 also accept the -T4 option but ignore it.
Also depend on xz-utils instead of on pxz.

* live-build/ubuntu-core/hooks/00-uid-gid-fix.chroot_early: add new "input"

Any change to either the initial set of users and groups or to the
post-package-install set will now be fatal to the image and will require

chroot_early hook.
* Bump dependency on live-build accordingly.
* Update the setup_user hook to also take care of gshadow.
work properly because it doesn't allow for signing key configuration.
Rename it to the more domain-specific EXTRA_PPAS (which is now a
space-separated sequence of <ppa-owner>/<ppa-name> pairs), and fetch
signing keys for those from Launchpad using python3-software-properties.
android-tools-fsutils dependency being architecture-specific, which
relieves us of having to port it to new architectures which don't care
about Android.
