signal/powerpc: Specialize _exception_pkey for handling pkey exceptions
Now that _exception no longer calls _exception_pkey it is no longer
necessary to handle any signal with any si_code. All pkey exceptions
are SIGSEGV with paired with SEGV_PKUERR. So just handle
that case and remove the now unnecessary parameters from _exception_pkey.
