parser: add dbus to the default features abi

Browse Source 
This fixes a regression introduced by the abi patches for policy that
is not tagged with an abi rule.

Specifically if the current apparmor (apparmor 3) is used with a
kernel that supports unix rules, and policy has network rules but has
not been updated to use abi rules, without this patch the policy unix
rules will stop working and unix mediation will not be enforced.
