selftests/powerpc: Skip earlier in alignment_handler test
Currently the alignment_handler test prints "Can't open /dev/fb0" about 80 times per run, which is a little annoying. Refactor it to check earlier if it can open /dev/fb0 and skip if not, this results in each test printing something like: test: test_alignment_handler_vsx_206 tags: git_version:v4.18-rc3-134-gfb21a48904aa [SKIP] Test skipped on line 291 skip: test_alignment_handler_vsx_206 Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Acked-by: Andrew Donnellan <andrew.donnellan@au1.ibm.com>
