More 3.7 tests failing unpredictably

[terriko]

Saw these failing in a few places in the pull requests over the weekend:

=========================== short test summary info ============================
FAILED test/test_extractor.py::TestExtractFileRpm::test_extract_file_rpm - Ru...
FAILED test/test_extractor.py::TestExtractFileRpmWithZstd::test_extract_file_rpm
FAILED test/test_helper_script.py::TestHelperScript::test_scan_files_single
===== 3 failed, 359 passed, 344 skipped, 113 warnings in 75.58s (0:01:15) ======

I'm starting to wonder if we need to just not run the extractor or helper script tests at all on 3.7 or what. These don't make any sense.
