build: verify for H264 MVC and H265 SPS

Currently the H264 and H265 parsers look for MVC and SPS respectively, and
the required symbols for those were added in GStreamer 1.5

If we try to compile in GStreamer < 1.4, without enabling the builtin codec
parsers, the compilation fails, because the lack of those symbols.

This patch verifies if the installed H264 and H265 parsers have those symbols. If
they do not, the specific built in codec parsers are enabled and used.
