[Buildroot] [git commit] chrony: systemd support

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=c6946f24cc1e4cbb8aaff1a2192c1a95d539ca5d
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

systemd has its own NTP daemon, which must be disabled before
starting chrony. Possible (but unlikely) conflict with openntpd
is not marked in either package.
