x11: promote libxkbfile; clear build dirs stranded by the wip move

kcms/keyboard links X11::xkbfile (CMakeLists.txt:37) and cmake aborted with
"Target kded_keyboard links to X11::xkbfile but the target was not found".
libxkbfile was sitting in recipes/wip/x11; promoted, given its util-macros
dependency, and wired into plasma-desktop and the config.

Also clears 9 build directories stranded by the earlier `git mv` out of wip.
Autotools bakes the absolute srcdir into its generated Makefiles, so a moved
recipe keeps building against a path that no longer exists:
  No rule to make target
  '.../recipes/wip/x11/libxkbfile/source/src/cout.c', needed by 'cout.lo'
The cook-side auto-invalidation added earlier only inspects CMakeCache.txt, so
autotools recipes are not covered by it -- these were latent failures that
would have surfaced one package at a time (libx11, libxcb, libxdmcp, libxft,
libxrender, x11proto, x11proto-kb, xcb-proto, xtrans).

Verified: cook libxkbfile - successful, libxkbfile.a staged.
