powerpc/signal32: Remove impossible #ifdef combinations
PPC_TRANSACTIONAL_MEM is only on book3s/64
SPE is only on booke
PPC_TRANSACTIONAL_MEM selects ALTIVEC and VSX
Therefore, within PPC_TRANSACTIONAL_MEM sections,
ALTIVEC and VSX are always defined while SPE never is.
Remove all SPE code and all #ifdef ALTIVEC and VSX in tm
functions.
