syscalls/fanotify: New test for fanotify user limits

Check that fanotify groups and marks limit are enforced correctly.
If user ns is supported, verify that global limit and per user ns
limits are both enforced.

In older kernels, the groups limit per user is hardcoded 128.
In recent kernels, the global limits can be configured via
/proc/sys/fs/fanotify/max_user_* and can be further restricted
per user ns via /proc/sys/user/max_fanotify_*.
