Replace ntpdate with systemd's timesyncd

Previously NTP was setup via ntpdate which resulted in a situation on
most systemd installations where NTP was effectively being setup twice
because timesyncd is usually enabled by default. This effectively
renders setting up ntpdate redundant as what it does is already done
by timesyncd. Being that Hestia only supports systemd installations the
most logical resolution is to replace ntpdate with timesyncd setup
during installation. That is what I try to do here.
