Subject: rpi: fix build

Runtime untested, because I get this:

  [vo/rpi] Could not get DISPMANX objects.

This happened even when building older git versions, and on a RPI image
that hasn't changed in the recent years. I don't know how to make this
POS work again, so I guess if there's a bug in the new code, it will
remain broken.
