Sysinstall now offers the installation of a keymap early in the game!

Not all mappings are supported, most languages come only with one
encoding since this should be sufficient to get up & running in using
sysinstall, and we are already pretty tight on space.  (My previous
commit has already bumped the boot MFS size by another 50 KB for
this.)

This feature requires the `kbdcontrol -L' i've just committed.  Plain
text keymaps and the entire scanner are overkill for sysinstall.

Also updated the list of available keymaps while i was at it.
