chrony: fix uci NTP access configuration

The chrony interface hotplug script reuses the handle_allow function
from the init script to allow NTP access on interfaces specified in uci.
The function requires /lib/functions/network.sh. Include the file in the
hotplug script to make the function work as expected.
