matchbox-wm: fix icon handling on 64-bit hosts

Xlib has a historical quirk where 32-bit values are returned in longs (but
always hidden through a cast).  On 32-bit machines this doesn't matter but on
64-bit this leads to problems.  Bump SRCREV to integrate a fix from upstream.

Also, drop the conditional configure_fix.patch, it was integrated long ago.
