re: Moving expat and a few other libraries to the base system

[matthew green <mrg%eterna.com.au@localhost>]

   Joerg also mentioned that two more libraries could move too:
    freetype
    fontconfig
   
   What do other think about such changes?


let's revert this when we have real syspkgs, but do it for now.  the
issues are more annoying than dealing with having these 3 packages
always included.

at the very least, expat should move.
