intel-media-sdk: Search ONEVPLRT in /run/opengl-driver/lib

Browse Source 
Patch Intel Media SDK to discover and dispatch to
`/run/opengl-driver/lib/libmfx-gen.so.1.2`.

This allows applications which depend on `intel-media-sdk` to use hardware
acceleration through `onevpl-intel-gpu` provided that it was added to
`hardware.opengl.extraPackages`. oneVPL-intel-gpu is the only supported
acceleration driver for newer Intel GPUs, meaning all integrated GPUs starting
with Alder Lake S/P.

This is important as applications may still want to build against
`intel-media-sdk` to support hardware acceleration on all Intel GPUs from
Broadwell to Rocket Lake and now newer platforms through oneVPL-intel-gpu.

E.g. the default build of ffmpeg > 6 will use `intel-media-sdk` rather than
`oneVPL` directly to support Intel Quick Sync on a larger number of systems.
