Checking lists for unavailable packages.

There is little use, but a lot of noise.

Unavailable metapackages will be removed from the list.
A warning will be displayed in the log.

Creates systemd-resolved symbolic link to /etc/resolv.conf

1) systemd-settings-disable-kill-user-processes - server systems should not
   kill processes after user exit;
2) apt-scripts - for apt-dedup;
3) update-kernel - to update kernel on vm cloud image.

When the save-profile is executed, the .work directory already exists.

For vm and ve targets do not require the vconsole-setup-kludge package.
For them the problem displaying non-ASCII characters in tty is not actual.

Simple grub image with grub theme.

Top item is no need to set a default. Also, this is no longer
possible, as some items are not available for all grub variants.

mkimage to run сlean/distclean successfully requires .work/.cache
and .work/.out directories.

If GRUB_UI variable is set, the gfxterm config will be added, which
in turn will lead to a build error on an unsupported architecture.

Use our own volumes profile instead of volumes-profile-regular:
it's simple and we are fixed some issues in that way:
- Don't create RAID.
- ALT bug #34520.

But don't install it by default.
