powerpc: Fix string library functions

The powerpc strncmp implementation does not correctly handle a zero
length, despite the claim in 3b789942923915e17998e2a012bdecaf828decf1
(Add hand-coded assembly strcmp).

Additionally, all the length arguments are size_t, not int, so use
PPC_LCMPI and eq instead of cmpwi and le throughout.
