ktime_get_snapshot() is replaced by ktime_get_snapshot_id() which allows to
request a particular CLOCK ID to be captured along with the clocksource
counter.

Convert the usage in kvm_get_ptp_time() over and use the new
system_time_snapshot::sys field, which holds the system timestamp selected
by the CLOCK ID argument.

No functional change intended.
