You could patch trezor-agent with something like

  # Python syntax might be incorrect
  if sys.argv[0] == ".trezor-gpg'
    sys.argv[0] = "trezor-gpg"
  device_name = os.path.basename(sys.argv[0]).rsplit('-',1)[0]

Would that work?

FWIW, there's 'wrap-program' and there is 'wrap-script'.
wrap-script is less likely to cause errors here (it doesn't rename the 
executable)
but less general.  Maybe wrap-script can be used instead of wrap-program?
