gst-check.m4: drop REQUIRED arg to AG_GST_CHECK_GST_PLUGINS_{GOOD,UGLY,BAD,FFMPEG}

Since .pc files for these modules only exist in uninstalled setups, if at all,
it doesn't really make sense to *require* their presence (or that particular
version). Code (e.g. unit tests) still needs to check element/plugin availability
and versions at runtime, since that's what's required for installed setups
anyway.
