Makefile: prevent default build rules being used on FFmpeg files

Browse Source 
After adding .o files to the dependencies of FFmpeg .a files make
tried to build those .o files with default rules before recursing to
the FFmpeg subdirs. Fix this by adding a dummy rule. Also fix
incorrectly placed parentheses in the command creating the FFMPEGFILES
list. That resulted in some files being listed multiple times,
triggering warnings from the dummy rule.
