package/connman: adapt to systemctl preset-all

connman has two services
* connman.service which is the real daemon
* connman-wait-online.service which is a sync point for network-online.target

Only the first one was enabled. This adaptation enables both.

Not enabling connman-wait-online.service is probably a bug
