closes #531

This PR contains a few changes (each in a separate commit):

  • adds fixtures and tests for parsing cpu vulnerabilities from sysfs, fixes the typo in the vulnerability string
  • switches to using a map of vulnerabilities instead of a slice (makes working with the result easier, e.g. when testing)
  • switches to using encoding of the state
  • adds license in the test file
  • adds linux build flags
  • adds test cases for vulnerable state, brings state string to lower cases (to try and make it case insensitive)

Minor nits, otherwise great.

rebased onto upstream

edit: due to unrelated failures in the CI

the codespell job is failing, but it's unrelated to this change

Here's the job definition:

procfs/.circleci/config.yml

Lines 38 to 45 in abbfda0

codespell:
docker:
- image: circleci/python
steps:
- checkout
- run: sudo pip install codespell
- run: codespell --skip=".git,./vendor,ttar,fixtures.ttar,./fixtures,go.mod,go.sum" -I scripts/codespell_ignore.txt

the docker image hasn't changed recently: https://hub.docker.com/r/circleci/python/tags

codespell pip package was updated yesterday: https://pypi.org/project/codespell/#history

I think this is unrelated and should be handled in a separate issue/PR. I'll open a separate one

Going to ignore the codespell, it's fixed in HEAD.
