[pkg-wine-party] Fix for kfreebsd-i386 issue, please test

[Hilko Bengen <bengen@debian.org>]

A set of four patches for FreeBSD-kernel based systems seems to fix
the bug described in #672415. (At lease I was able to run wine cmd.exe
in a KVM virtual machine running kfreebsd-i386.)

Once 1.2.3-0.2 hits unstable, I intend to do a 0-day NMU of a
1.2.3-0.3 package which which contains this fix. At that point, none
of the current release-critical bugs will be left. Any objections?
