Thanks @LillianaPrikler <at> gmail.com for all the help :D, I thought about
this a bit more and looked at all the utility stuff in
BubblewrapLauncher.cpp. I realized that the correct thing to do here
is to simply mount the LIBVA_DRIVERS_PATH paths. I'm wondering if this
shouldn't be part of the gstreamer default mounts even upstream? along
with the LOCPATH mount.

 This is a Guix-specific patch not meant to be upstreamed.
