meta-agl-core: Improve connman-wait-online usability

Changes:
- Ship connman-wait-online in packagegroup-agl-core-connectivity.
- Add installation of a systemd drop-in configuration file for
  systemd-networkd-wait-online when VIRTUAL_RUNIME_net_manager
  is set to connman that will disable it.  This is required to
  avoid boot hangs if a unit does add a dependency on the
  network-online target.  The approach is not ideal, but it is
  not clear how to avoid systemd-networkd-wait-online getting
  enabled without actually modifying the systemd-networkd unit.
