variant: check for gen_config on the PATH before running
This ensures that gen_config is available before the script runs, and
fails with instructions for adding it if it is not available.
BUG=b:172835923
TEST=remove gen_config from path and run fw_build_config.sh directly,
then again after adding to path with the instructions from the script.
