Set the process title where possible

[Gerald Pfeifer]

Kris Moore submitted an earlier version of this patch which was checking
for FreeBSD.  This updated version uses autoconf to check for the presence
of the setproctitle system call and uses this if applicable.  Kris acked
this version.

Our colleagues from PC-BSD especially would appreciate to see this in the
next release of Wine.
