Robotics related package list, feature and live-robo target added.
mediacheck: drop firmware/udev as well

These aren't needed in this subprofile but can sneak in
via e.g. SYSTEM_PACKAGES.
mediacheck: purge more packages

No use to hunt make or diff file-by-file.

Well this chroot should have been more lean
in the first place (or a few files in initrd)
but life is short so better use/baby/steps.
syslinux: fix mediacheck label for gfxboot

Whoops, the very first build of a real distro with gfxboot
has shown that the label isn't picked up there... and things
are actually worse: iso.needscheck gfxboot test seems to look
up "check=1" in sectors where it might have been landing back
then but it's just not there by now; some kludgery is due in
branding-altlinux-sisyphus unfortunately.
