systemd-timedated discovers NTP services from ntp-units.d/*.list.
Buildroot's chrony package never installs one: on a systemd image
without timesyncd, 'timedatectl status' reports
NTP service: n/a
and 'timedatectl set-ntp on' fails with
Failed to set ntp: NTP not supported
even though chronyd is running.
Install 50-chrony.list, following the convention set by Debian,
Fedora and Arch, so timedatectl can manage chrony.

It's really weird that I can't find this patch on patchwork.buildroot.org.
