[OE-core] [PATCH 2/2] connman: Don't use a blanket "allow" D-Bus policy

[Jussi Kukkonen]

There are already "allow" rules for root and conditionally xuser to
send messages to connman: there should be no reason for a default
allow policy.

Also, conditionally add a policy to allow xuser to send to the
connman vpn service (similar to main service).
