Tests: adjusted mp4 tests to use libopenh264 encoder if available.

Instead of specifically requesting libx264, the h264 codec is now requested,
so the default encoder for the codec will be used.  Notably, this ensures
that tests will properly work on Fedora, where libopenh264 is used instead
of libx264.
