Remove unused argument in print statement

[prestonvanloon]

Resolves #836

This argument was not used. I'm not sure if it was useful so this PR proposes to remove it entirely.

I'd be happy to add to the print statement in this PR if anyone feels differently.

I think I would instead modify this to:

print(("%s not using checked in configs; '%s' was picked/selected as a candidate matching config for Bazel %s from whose list of compatible configs are %s" +
               "but it does not match " +
               "the 'env = %s', 'config_repos = %s', " +
               "and/or 'create_cc_configs = %s' passed as attrs") %
              (
                  name,
                  config,
                  bazel_version,
                  str(bazel_compat_configs),
                  env,
                  config_repos,
                  create_cc_configs,
              ))
