gstreamer: fix argument parsing when using Bison 3

Remove the argument fix patch and add a patch which fixes the
grammer.y Bison input file. YYLEX_PARAM seems to be no longer
supported and has been replaced with %parse-param which has
been introduced already in 2003.

This fixes a segmentation fault when launching gst-launch-0.10.
