libsndfile: Fix missing external library support

The recent upgrade regressed codec support since opus is missing and
this caused several codecs to be disabled. Add a patch to work around
the issue whilst it is discussed with upstream.

+We don't have opus in OE-Core which causes all the external libs to be disabled 
+silently. The silent issue is discussed in the link below and hints a patch
+to make things configurable may be accepted.
+
+This patch removing the opus piece at least gets most of the functionality
+we previously used back whilst the issue is discussed.
