Xorg: Link XKB DDX library after core server libs

libxorgxkb.a contains a number of libraries which are used by XKB action
code to call back into the DDX, e.g. for VT switching, termination, grab
breaking, et al.  Make sure libxkb.a comes first in the link order, so
it can mark XkbDDX* as used in order for the linker to not discard them.
