[PATCH] tests/userfaultfd: fix invalid flag testing

[Sven Schnelle]

With linux commit 37cd0575b851 ("userfaultfd: add UFFD_USER_MODE_ONLY")
flag with value 1 is now a valid flag. This commit changes it to 2 as
that one is the next available. It doesn't implement any testing of
UFFD_USER_MODE_ONLY though.
