[Cin] QSV render tests 20% faster with RPM vs AppImage

[Terje J. Hanssen]

I did a few hevc and av1 OSV render tests using the latest RPM w/oneVPL 
on Leap, to compare it with my own AppImage.
To get the AppImage from Slowroll to run om Leap, I had to add-install a 
newer version libFLAC12.

The machine is AlderLake w/Arc A750 gpu
The OS root drive is on a std SATA disc, while the video files are 
read/written to a fast M.2 disc.

Results:

hevc_qsv_8b420.mp4
** rendered 5972 frames in 19.255 secs, 310.153 fps (RPM)
** rendered 5972 frames in 23.798 secs, 250.945 fps (AppImage)

av1_qsv_8b420.mp4
** rendered 5972 frames in 18.612 secs, 320.868 fps (RPM)
** rendered 5972 frames in 21.470 secs, 278.156 fps (AppImage)

In average rendering is ca. 20% faster with the RPM.
I did also additional test with the AppImage on Slowroll and got a bit 
faster rendering, but not so fast as with RPM on Leap.
