Add link between one-context.service and systemd-networkd.service

also updated 00-network and 05-hostname

One-context.service should be linked to systemd-networkd.service,
tying to do this using the Wants flag.  Additionally since
one-context.service should now run before systemd-networkd.service
it's superfluous to restart the unit, this was edited out of
00-network.  05-hostname was edited to use the hostnameclt, the
echo style can probably be removed.
