common: handle match for config intf added/removed

When the configuration interface for any device is added or removed as
part of dynamic configuration (via EM) the software manager has to
handle the dbus match and add or remove devices as necessary.

When an update is in progress, the device is not removed,
even if the configuration was removed.

Tested: On Tyan S8030 with bios software updater

For testing add/remove of configuration interfaces, the configuration
was probed on the powersupply FRU.

In case of InterfacesAdded:
