fix(mounts): Reposition gryphons, one more time

Third time's the charm. This version uses a 5x, 3y offset, preserving the wingtip. I've also moved the skeleton gryphon's wing so it emerges from the shoulder similar to the fleshy gryphons' wings, no longer obscuring the avatar's face. Now I'm done for reals; more expert pixelists can tweak from here ^.^;
