Robert Löhning 90f0d522bf Fuzzing: Don't explicitly restrict sizes before loading images
Since Qt 6.0, QImageIOHandlers by default take care of this themselves
by not allocating more than 128 MiB for an image.

This change will not significantly reduce code coverage of the fuzzer
because QImage::loadFromData() calls QImageReader::read() which does
everything QImageReader::size() does except for returning the read size
in the end. On the other hand, it will speed up the execution because
the same image will not be read twice by different QImageReaders anymore.
