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

[Phyllis Smith]

Slower AppImage is to be expected, but still disappointing.  Bottom line is
that users who can take advantage of Andrey's RPMs should always do so.
Besides being faster, it provides more capabilities and opportunity to make
some minor side changes.  Thank you, Terje, for doing the tests and passing
along this information.
