Linux AMD crash when src blit region outside framebuffer

Linux AMD has a crash on an assert in the mesa driver that the source rectangle
for blitFramebuffer be inside the framebuffer. Add Linux AMD to the existing
workaround for this case.
Note: this will duplicate some work on Linux AMD if the blit call is outside
the framebuffer and also very large (the adjustSrcDstRegionBlitFramebuffer
workaround)
