powerpc: Fix string library functions

The powerpc strncmp implementation does not correctly handle a zero
length, despite the claim in 0119536cd314ef95553604208c25bc35581f7f0a
(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.
