accountsservice: depend on default-dbus-system-bus | dbus-system-bus

Luca Boccassirequested to merge
bluca/accountsservice:dbus_deps into master

Allows users to install only a single system bus implementation. Prefer the default (dbus-daemon), and leave the old dbus package as the last option to facilitate no-changes backports.
