Make output of generate_operator_out reproducible

As part of using python_binary_host, argv[0] is often the extracted
python script in a temporary directory. Just hardcode the
generate_operator_out.py name so that a random directory isn't encoded
in the output.

Test: m art_compiler_operator_srcs; inspect output
