x11/xfree86_xkb_xml plist fix related to X.Org upgrade

[Dejan Lesjak]

Hello,

As part of X.Org upgrade, some cleanups are being made to mtree for /usr/X11R6 
directory. Subirectories lib/X11/xkb/rules and lib/X11/xkb are being moved 
from mtree to pkg-plist file of xorg-clients port as it is the one that uses 
those. Apart from it, x11/xfree86_xkb_xml also uses them and will have to 
remove them by itself. However as XFree86 ports still use the old mtree file, 
until they are changed with the next upgrade, a temporary conditional is 
required. The patch that does that is here:
http://www.ijs.si/~lesi/xorg/upgrade-682/xfree86_xkb_xml_2.diff
Please let me know if this change is acceptable, I intend to commit it 
together with X.Org ports upgrade.
Thanks!
