[packman] libmms and openSUSE-12.1

[todd rme]

I notice that building for libmms (in Essentials) is disabled for
openSUSE-12.1.  Could someone please enable building of this package
on openSUSE-12.1?

The version of libmms in Essentials has a critical improvement over
the version shipped with openSUSE-12.1: it has a -32bit compatibility
version (libmms0-32bit).  Without this,
gstreamer-0_10-plugins-bad-32bit is uninstallable on openSUSE-12.1.
