ktime_get_snapshot() resolves to ktime_get_snapshot_id(CLOCK_REALTIME). Make it obvious in the code and convert the readout to use the snapshot::sys field instead of snapshot::real, which is going away.
Similar to the PPS generators, avoid the more expensive snapshot when CONFIG_NTP_PPS is disabled. No functional change intended.
