fanotify: support watching filesystems and mounts inside userns
An unprivileged user is allowed to create an fanotify group and add
inode marks, but not filesystem, mntns and mount marks.
Add limited support for setting up filesystem, mntns and mount marks by
an unprivileged user under the following conditions:
1. User has CAP_SYS_ADMIN in the user ns where the group was created
2.a. User has CAP_SYS_ADMIN in the user ns where the sb was created
OR (in case setting up a mntns mark)
2.b. User has CAP_SYS_ADMIN in the user ns associated with the mntns
