live: factor out x11-autologin

Hardly belonged there in the first place and became a culprit during armh branch development since it had to be forked in an ugly manner; move to rootfs hooks and be done with it. VM images will be able to benefit either *but* installed systems might have some trouble when this is implemented: http://lists.altlinux.org/pipermail/devel/2013-May/197447.html Split off use/live/x11 as a common free/proprietary ground either (this refactoring had to be performed in parallel with x11 feature being revamped, diffs quickly became intertangled unfortunately).
