meson: Re-add auto option for omx

This re-adds the auto option for omx, without it we default to tizonia
and the build fails almost immediately, this is especially obnoxious
those building a driver that doesn't support the OMX state tracker to
begin with.

v2: - Only define OMX_FOO for auto cases if the dependencies are found.
      This fixes building tizonia with auto (Julien, Eric)
