Subject: [PATCH] Allow domain use userfaultfd over all domains

Reference: https://gitbub.com/fedora-selinux/selinux-policy/commit/3befcf9bdea867fca0d980871e251191fe234586
Conflict: NA

Until now, all processes were allowed to use userfaultfd as well other
anon_inodes to get a file descriptor from the same domain.
Since this commit the permissions are allowed between different domains.
