Core package removal: liboldX, libxkbui

[Adam Jackson <ajackson redhat com>]

Neither of these libs is used at all in either core or extras, AFAICT. 
liboldX is ABI compatibility for X10 applications, which would be 
shocking to find since X10 never built on Linux to begin with.  libxkbui 
is used from the xorgcfg utility, but that's not built in Core; I don't 
know of any other application that uses it.

Both will be dropped from Core in tomorrow's rawhide.  If someone really 
wants to revive libxkbui for some reason, it'd be a fine candidate for 
Extras.
