include/ceph_features: note more kernel versions

Despite both MONNAMES and MONENC being pre-argonaut feature bits and
the kernel client implicitly assuming argonaut since 5.0, its monmap
decoding routine didn't handle MONNAMES and MONENC until 5.11 (when it
became necessary as part of msgr2 support).
