93aa285376 nixos: fix #48917 by setting SYSTEMD_TIMEDATED_NTP_SERVICES
Setting this variable in the environment of systemd-timedated allows
'timedatectl' to tell if an NTP service is running.

Closes #48917.

1590461887 ntp: make timesyncd the new default
- most nixos user only require time synchronisation,
  while ntpd implements a battery-included ntp server (1,215 LOCs of C-Code vs 64,302)
- timesyncd support ntp server per interface (if configured through dhcp for instance)
- timesyncd is already included in the systemd package, switching to it would
  save a little disk space (1,5M)

b61d4ac6a5 ntpd: Fork into the background
With -n, ntpd will write log messages to both syslog and stderr, which
is ugly.

ea9d391bb5 Fix ntpd
Since the 4.2.8 upgrade, ntpd is broken on NixOS:

  Dec 28 19:06:54 hagbard ntpd[27723]: giving up resolving host 1.nixos.pool.ntp.org: Servname not supported for ai_socktype (-8)

This appears to be because DNS resolution doesn't work in chroots
anymore (due to /etc being missing). So disable chroots for now. It's
probably better to use systemd's containment facilities anyway.

29027fd1e1 Rewrite ‘with pkgs.lib’ -> ‘with lib’
Using pkgs.lib on the spine of module evaluation is problematic
because the pkgs argument depends on the result of module
evaluation. To prevent an infinite recursion, pkgs and some of the
modules are evaluated twice, which is inefficient. Using ‘with lib’
prevents this problem.
