Code is qt6 only now. Remove unused check

Prior libavif 1.0, quality was set using two numbers
(minQuantizer and maxQuantizer).
New versions of libavif recommend using
new/single quality parameter instead.
Compression using the new settings is different
compared to the old.
For example, new quality 68 gives similar compression
like old default 52.
