modemfwd_switches: reflect new interface

get_usb_ids is no longer necessary since we supply this information
in a manifest, and get_carrier_fw_info has been expanded to return
all firmware version information.

CQ-DEPEND=CL:765088
BUG=b:68816453
TEST=emerge modemfwd and deploy, ensure that the L850-GL with the
  new helper uses the main firmware version that does not contain
  any carrier information
