Fix #66882: imagerotate by -90 degrees truncates image by 1px

Contrary to the external libgd, the bundled libgd doesn't use optimized
rotation algorithms for negative square angles. We fix that now.

There are other improvements in gdImageRotateInterpolated() in the external
libgd. I'll leave them out for now, in the hope that we'll be able to rejoin
the two libraries rather soon.
