use struct pt_regs * rather than void * for powerpc[64] sigcontext regs

this is to match the kernel and glibc interfaces. here, struct pt_regs
is an incomplete type, but that's harmless, and if it's completed by
inclusion of another header then members of the struct pointed to by
the regs member can be accessed directly without going through a cast
or intermediate pointer object.
