Fix #72696: imagefilltoborder stackoverflow on truecolor images

We must not allow negative color values be passed to
gdImageFillToBorder(), because that can lead to infinite recursion
since the recursion termination condition will not necessarily be met.

(cherry picked from commit 863d37ea66d5c960db08d6f4a2cbd2518f0f80d1)
