Subject: [PATCH 0/6] selftests/mm: Some cleanups from trying to run them

I never had much luck running mm selftests so I spent a couple of hours
digging into why.

Looks like most of the reason is missing SKIP checks, so this series is
just adding a bunch of those that I found. I did not do anything like
all of them, just the ones I spotted in gup_test, mmap, userfaultfd and
memfd_secret.
