selftests/mm: sigbus-wp test requires UFFD_FEATURE_WP_HUGETLBFS_SHMEM
commit 105840ebd76d8dbc1a7d734748ae320076f3201e upstream.
The sigbus-wp test requires the UFFD_FEATURE_WP_HUGETLBFS_SHMEM flag for
shmem and hugetlb targets. Otherwise it is not backwards compatible with
kernels <5.19 and fails with EINVAL.
