media-video/mpv: skip ffmpeg suite for tests

Could adjust or skip only with USE=-vulkan wrt bug #924276, but ffmpeg
tests have caused other issues before depending on ffmpeg version and
BE arches (seen on hppa, and formerly on ppc64be). They also do not
seem very interesitng downstream as their purpose seem to be to track
subtle changes in ffmpeg versions without necessarily meaning there is
a notable runtime issue.

Was going to skip only img-format but the other ffmpeg test has also
caused issues on e.g. hppa and meson still doesn't allow to skip
specific tests currently (only suites).

hppa still has the timer test failing which is likely an actual
problem though (not really looked into but it's unkeyworded now).
