[LTP] [PATCH v1 2/3] security/dirtyc0w_shmem: Fix compile-time absence of UFFD_FEATURE_MINOR_SHMEM

[David Hildenbrand]

Without UFFD_FEATURE_MINOR_SHMEM, we'd currently let the parent run into
a timeout because we don't make the checkpoint happy, failing the
testcase instead of skipping it as TCONF.

Let's make compilation always work by including include/lapi/userfaultfd.h.
