setproctitle() possibly never used on BSD systems

[chrfranke]

The commit 53e2009 possibly prevents that setproctitle() is used on BSD systems because these (at least FreeBSD) provide its prototype in the default <unistd.h> and do not provide a <bsd/unistd.h> or the related BSD compatibility lib.

Removing defined(HAVE_BSD_UNISTD_H) may do the trick.

Thanks for reporting this, I'll sort this out in the next couple of days.

I've pushed a couple of changed that should fix this.
