scripts/config_converter: remove always empty subsystems

JSON configuration that does not contain a particular
subsystem is a valid one. If needed, the defaults are always
present in the subsystem itself.

accel, interface, net_framework, scsi, nbd do not have
legacy configuration to convert. Including those in the
output of config_converter does not serve any purpose.
