Fix run export substring check

Description

This PR fixes #5529.

It also adds a constraint to the test requirements file that was previously missing but is required to get a compatible version of py-lief, and it updates the gitignore for vim swap files.

One note that isn't directly related to this PR but did affect me is that the test requirements file is also missing a few additional requirements.

• pytest: This one should definitely be there to run the tests. I do see it in the requirements-ci.txt file, but I'm not sure what the purpose of requirements.txt is if not to include everything needed to at least run the tests locally as well.
• pytest-cov: This probably shouldn't be a hard requirement, but it currently is due to the hardcoded addopts in pyproject.toml.
• binstar_client: I guess this is a legacy pre-anaconda project, so I'm not sure where it should be coming from or if it should still be used here.

I also need a bit of help figuring out the right way to test this. I've verified the result manually, but I couldn't find an easy programmatic way of doing this with conda_build APIs since rendering isn't sufficient so we can't just inspect metadata. The best I could come up with is running the build and then manually extracting and inspecting the metadata of the result. I'm not sure if there is a better way, though.

The test failures look completely unrelated to my change, but I do still need some help with the things I listed above before this PR would be ready.
