tst_qpainter: change the FP exception block-list to a pass-list

Browse Source 
We should prefer to test this unless we know it won't work, but this is
very hardware and implementation-dependent anyway. So I declare that
we'll only guarantee FP exception cleanliness on a best-effort basis for
a few platforms.

The notable difference in this commit is the removal of QNX. I don't
know why it began producing an FP exception with one of my changes, but
since the toolchain isn't public, I can't debug and will not devote any
time to figuring it out. If users of QNX require this, then someone with
interest in that OS will need to spend time after my changes integrate.
