XKB: Remove component listing support

No-one uses this - not xkbcomp, not GNOME, not KDE.  The preferred way
to deal with component listing (which gives you RMLVO rather than
KcCGST) is to use the XML files on the client side.

Indeed, a couple of hours after making this commit, it emerged that all
*.dir files built with xkbcomp 1.1.1 (released two years ago) and later
have been catastrophically broken and nearly empty.  So I think that's
reasonable proof that no-one uses them.
