selftests/powerpc: Add more version checks to alignment_handler test
The alignment_handler is documented to only work on Power8/Power9, but we can make it run on older CPUs by guarding more of the tests with feature checks. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Reviewed-by: Andrew Donnellan <andrew.donnellan@au1.ibm.com>
