[meta-networking][PATCH] chrony: install chrony-wait.service

[pdmorrow@gmail.com]

From: Peter Morrow <peter.morrow@microsoft.com>

Any systemd service which needs to wait on ntp synchronization before
starting can order themselves after chrony-wait.service.  It's useful
to install this service as part of the recipe as it saves needing to
install it via a bbappend file.  Note that even if the service is
installed no start up delay is introduced unless another service
orders itself after the systemd target time-sync.target.
