live: add use/live/runapp

Add the possibility to directly configure the desktop app for livecd kiosk mode to start. This should have been done as soon as livecd-runapp hit the streets -- livecd-{0ad,fgfs} definitely must go as adding a line into config is trivially done near the only place that requires them (conf.d/live.mk). TODO: might be more generally useful for vm/* too, take this out into a separate feature then. Edited: https://lists.altlinux.org/pipermail/devel-distro/2022-September/002889.html
