[PowerPC] Force entry alignment in .got2

Implement Bill's suggested fix for 32-bit targets for PR22711 (for the
alignment of each entry). As pointed out in the bug report, we could just force
the section alignment, since we only add pointer-sized things currently, but
this fix is somewhat more future-proof.
