Replace NetworkManager by Connman.

New dracut update fails when building initramfs for live ISO when NetworkManager is present, as it now depends on systemd hook.
Void Linux didn't take a decision yet about what they'll do about this, but we decided to nip the problem in the bud dropping NetworkManager in favor of Connman.
connman-gtk GUI was chosen even for Qt desktop environments, because is easier to understand for new users than cmst.
Fixes void-linux#296.
