dbus-broker: Declare runtime conflict with dbus

The user should now be able to choose the preferred runtime D-Bus
implementation with VIRTUAL-RUNTIME_dbus variable. In order to avoid
situation where both Freedesktop.org's dbus and dbus-broker are pulled
into the same root filesystem, add conflict declaration which will help
to detect the problem already during the Yocto build.
