Add one more debugging option to see transformation on font-matching

just setting FC_MATCH=3 shows a lot of information and hard to keep on track for informamtion
which is really necessary to see. to use this more effectively, added FC_DBG_MATCH_FILTER to
see for what one really want to see. it takes a comma-separated-list of object names.
If you want to see family name only, try like this:

FC_DBG_MATCH_FILTER=family FC_DEBUG=4096 fc-match

debugging output will be filtered out and see family only in the result.
