[1/2] kunit: tool: add subscripts for type annotations where appropriate
Commit Message
E.g. for subprocess.Popen, it can be opened in `text=True` mode where it
returns strings, or `text=False` where it returns bytes.
To differentiate, you can annotate types as `Popen[str]` or
`Popen[bytes]`.
This patch should add subscripts in all the places we were missing them.
