Fix recording ENOENT: try absolute ffmpeg paths before bare 'ffmpeg'

ffmpegPath() short-circuited on the bare 'ffmpeg' candidate, so the absolute
Homebrew/system paths were never checked. From a terminal PATH covers it, but
the packaged app launched from Finder has a minimal PATH: stopping a
recording failed with 'spawn ffmpeg ENOENT'. Absolute candidates now win;
bare 'ffmpeg' is the last resort.
