Build media plugins for the secondary arch.

These are used when an app uses BMediaFile/BMediaTrack, which leads to
the plug-ins being instanciated on the application side.

* Fixes one more part of #10049 (media add-ons are still missing).
* Will probably not solve any real-world issue because of #4893.
