x86/pkeys/selftests: Fix pointer math
We dump out the entire area of the siginfo where the si_pkey_ptr is
supposed to be. But, we do some math on the poitner, which is a u32.
We intended to do byte math, not u32 math on the pointer.
Cast it over to a u8* so it works.
Also, move this block of code to below th si_code check. It doesn't
hurt anything, but the si_pkey field is gibberish for other signal
types.
