[Buildroot] [git commit branch/2021.02.x] package/webkitgtk: select missing multimedia deps

commit: https://git.buildroot.net/buildroot/commit/?id=071df79e1da57eb1a7870638562613d5b4cdb60c
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2021.02.x

Select a few missing multimedia related dependencies:

- BR2_PACKAGE_GST1_PLUGINS_GOOD_PLUGIN_AUTODETECT is needed for
  "autoaudiosink"; not having this element can cause a crash as
  it is used unconditionally.
- BR2_PACKAGE_GST1_PLUGINS_GOOD_PLUGIN_MATROSKA and
  BR2_PACKAGE_GST1_PLUGINS_GOOD_PLUGIN_VPX are needed for
  WebM video playback.
