These now inherit from a top-level package.mk
Options like use of the network can be enabled on a per package basis
This removes a lot of duplicate code and make the maintenace of these
Makefiles much easier

Added to Docker example as Swarm mode likes time sync.
Note uses pool.ntp.org at present, on some providers it
should use a different source.
Constraints not enabled as they seem to have an issue;
possibly trying to set before network is up.
