selftests/fs/mount-notify: build with tools include dir Copy the fanotify uapi header files to the tools include dir and define __kernel_fsid_t to decouple dependency with headers_install and then remove the redundant re-definitions of fanotify macros.

selftests/filesystems: create get_unique_mnt_id() helper Add helper to utils.c and use it in mount-notify and statmount tests.

selftests/fs/mount-notify: add a test variant running inside userns unshare userns in addition to mntns and verify that: 1. watching tmpfs mounted inside userns is allowed with any mark type 2. watching orig root with filesystem mark type is not allowed 3. watching mntns of orig userns is not allowed 4. watching mntns in userns where fanotify_init was called is allowed mount events are only tested with the last case of mntns mark.
