selftests/fs/mount-notify: Fix compilation failure.
Commit c6d9775c20 ("selftests/fs/mount-notify: build with tools include
dir") introduces the struct __kernel_fsid_t to decouple dependency with
headers_install.  The commit forgets to define a macro for __kernel_fsid_t
and it will cause type re-definition issue.

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.
