Environment variable-related test fixes #623

See the individual commits for details.

While I was working on implementing what was discussed here, I realized that there were other edge cases where environment variables could cause problems. For example, running YAMLLINT_CONFIG_FILE=/random/binary/file python -m pytest discover caused a bunch of new test failures. I decided to implement a more robust solution that fixes the problem for more than just test_run_with_user_global_config_file.

Fixes #605. Fixes #621.
