pps: Convert to ktime_get_snapshot_id()
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::systime and monoraw fields instead of snapshot::real and raw,
which aregoing away.
Similar to the PPS generators, avoid the more expensive snapshot when
CONFIG_NTP_PPS is disabled.
No functional change intended.
