Bjorn Neergaard 9a202e342b seccomp: always allow name_to_handle_at ...

This syscall is used by systemd to request unique internal names for
paths in the cgroup hierarchy from the kernel, and is overall innocuous.

Due to [previous][1] [mistakes][2] in moby/moby, it ended up attached to
`CAP_SYS_ADMIN`; however, it should not be filtered at all.

An in-depth analysis is available [at moby/moby][3].
