Build System: Fix issue with addons moduleinfo.

The build system now scans additional sources when generating
moduleinfo for menuselect.  Unfortunately the extra sources
for format_mp3 only exist if downloaded.

Use the Makefile macro 'wildcard' to allow moduleinfo generator
to ignore sources that do not exist.
