Clean up README.chromium

Most of the instructions here are super out of date. I've added a note
to view more up-to-date instructions in //media/ffmpeg/README, because
it's significantly easier to keep that file fresh with active commits
than it is to modify this one and pray it doesn't cause some insanity
when performing the roll (hopefully this change doesn't blow something
up).
