FreeBSD oaf fix

[Chris Toshok <toshok ximian com>]

Evolution has hung on startup on FreeBSD (all versions I've tested along
the 4.x branch, and I assume the 5.x stuff as well) for some time now. 
This patch to OAF (the oaf-stable-0-6 branch) fixes the problem.  I've
run evolution on Linux with the fix and haven't noticed a change.

Considering this fix isn't needed to keep things working on the other
platforms evolution supports (linux, solaris) there's obviously some
discrepancy in the handling of signal masks (specifically those which
block SIGCHLD) between these platforms.  Not sure which platform(s) are
the ones with the bug, honestly, or if the correct behavior is even
specified someplace.
