Bmcweb get/set the "NTP settings" on phosphor-settings.
phosphor-time-manager and phosphor-settings are responsible to sync the
settings with systemd-timedated. So the services like bmcweb and ipmid
will only have to get/set the property on phosphor-settings.

However, in order to avoid a race condition issue with NTP set, bmcweb
now directly uses systemd instead of routing through phosphor-settings.
As a result, there may be differences in the "NTP settings" between
phosphor-setttings and systemd-timedated. To address this, this commit
adds a match to monitor time sync method changes on systemd-timedated
and updates it to phosphor-settings.

Tested:
```
1. Get current NTP setting:
busctl get-property org.freedesktop.timedate1 /org/freedesktop/timedate1 org.freedesktop.timedate1 NTP
b true

busctl get-property xyz.openbmc_project.Settings /xyz/openbmc_project/time/sync_method xyz.openbmc_project.Time.Synchronization TimeSyncMethod -j
{
"type" : "s",
"data" : "xyz.openbmc_project.Time.Synchronization.Method.NTP"
}

2. Call method in systemd timedate, to change NTP setting:
busctl call org.freedesktop.timedate1 /org/freedesktop/timedate1 org.freedesktop.timedate1 SetNTP bb false false

journal log:
phosphor-time-manager[28150]: Time mode has been changed to xyz.openbmc_project.Time.Synchronization.Method.Manual
phosphor-time-manager[28150]: NTP property changed in systemd time service, update to phosphor-settings.
phosphor-time-manager[28150]: NTP mode is already the same, skip setting to systemd time service again.

3. Get NTP setting again, NTP in phosphor-settings is synced with systemd-timedated:
busctl get-property org.freedesktop.timedate1 /org/freedesktop/timedate1 org.freedesktop.timedate1 NTP
b false

busctl get-property xyz.openbmc_project.Settings /xyz/openbmc_project/time/sync_method xyz.openbmc_project.Time.Synchronization TimeSyncMethod -j
{
"type" : "s",
"data" : "xyz.openbmc_project.Time.Synchronization.Method.Manual"
}

4. Set property in phosphor-settings, to change NTP setting:
busctl set-property xyz.openbmc_project.Settings /xyz/openbmc_project/time/sync_method xyz.openbmc_project.Time.Synchronization TimeSyncMethod s "xyz.openbmc_project.Time.Synchronization.Method.NTP"

journal log:

phosphor-time-manager[28150]: NTP mode is already the same, skip setting to phosphor-settings again.
