Subject: interfaces: ifconfig: T2653: migrate to get_interface_dict() API

After switching from raw parsing of the interface options to get_config_dict()
this utilizes another utility function which wraps get_config_dict() and adds
other common and reused parameters (like deleted or bridge member).

Overall this drops redundant code (again) and makes the rest more maintainable
as we only utilize a single function.
