media-video/ffmpeg: Use main build for Chromium where possible in v4+

The main build is now compatible with Chromium, except when OpenCL is
enabled. I thought about keeping the build separate or adding to
REQUIRED_USE but in the end, I decided to let it work both ways. The
precise compatibility requirements may change over time so I have
added a build_separate_libffmpeg function.
