stage3 packages need to add into the installed system only.
Fix for commit 87cb4401.

Exclusive lists with mobile applications.

This must be done to ensure that its dependencies are not removed
after uninstalling the interactivesystem package. Relevant only
for systems installed from packages. Not relevant for live and
rootfs, since all packages will be marked as manually installed.

The package must be installed Live so that when built, the script
features.in/repo/live/image-scripts.d/90-repo-mirror will change
the mirror to the specified one.

This is needed for all rootfs.

postinstall.d/86-all-groups the script will be packaged into the
installer-common-stage2.

Some control that need to be set may appear after additional
installation of basic packages.

After the ability to use live to install a distribution from
packages was added, it turned out that no one installs these
packages.

These base packages are not installed by anyone else.
As a result, users have an empty home directory.
And think it is necessary to unify the basic content of
Live and the installed system.

The un-def kernel should be added to the image
at Evgeny Sinelnikov's <sin@altlinux.org> request.
Together with the un-def kernel, its modules, documentation,
and the installer-feature-cleanup-kernel-stage3 package
were added to keep only one kernel selected by the user
during installation in the installed system.

Some services that need to be enabled or disabled may appear after additional
installation of basic packages.
