Roll the existing patches into a distfile patch. In the course of doing so:

Fix the fix previously in patch-ah (for platforms where char is
unsigned by default) to not generate spurious EOF indications.

Improve the fixes previously in patch-a[bcdef] to put the game's state
file in $HOME/.craft instead of the current directory.

Use a consistent method to set $PREFIX instead of a mixture of
compiler flags, patching, and SUBST.

Use pkg-config to find libX11, and clean up some pkglint.
