CP-309762 Update ntp-dhcp server file path

xsconsole can set ntp to Use DHCP NTP Servers or Use Default NTP
Servers, Provide NTP Servers Manually. This is so-called dhcp
default and manual mode.

When switching from other modes to DHCP, the DHCP-provided NTP
servers should be added to the Chrony sources. Conversely, they
should be removed when switching away from DHCP.

When upgrade dom0 chrony version to 4, the chrony-dhcp server file
changes from `/var/lib/dhclient/chrony.servers.$interface` to
`/run/chrony-dhcp/$interface.sources`, the same with XS9.
