Clean up PPC CPU capabilities and Montgomery code.

ppc64-mont.pl (which produces bn_mul_mont_fpu64()) is unused on both
powerpc and powerpc64, so remove it. ppccap.c doesn't actually contain
anything to do with CPU capabilities - it just provides a bn_mul_mont()
that calls bn_mul_mont_int() (which ppc-mont.pl generates). Change
ppc-mont.pl to generate bn_mul_mont() directly and remove ppccap.c.
