Harden authorized keys a bit more (#17772)

Browse source 
sshd(8) list restrict as a future-proof way to restrict feature
enabled in ssh. It is supported since OpenSSH 7.2, out since
2016-02-29.

OpenSSH will ignore unknown options (see sshauthopt_parse in
auth-options.c), so it should be safe to add the option and
no-user-rc.
