GitHub Actions workflow for running GNU tar tests

[kaladron]

This checks out GNU tar and runs its test suite
against our built tar binary.

The hooks in autotest aren't working correctly,
so we manually overwrite the built binary with
our generated binary for testing.

Hi @sylvestre! I need guidance on this PR. =)

It's correctly showing that all tests are failing (I spot checked the logs, it's calling with "tar cf", which we don't handle)

How do we make the nice graph that you have for Coreutils? =)

Also, how do you have it set on uutils/coreutils to not show everything as failing on each PR? I cribbed the setup from coreutils, but I think I'm missing something in the setup.

[sylvestre]

the process is basically:

1. build with the right options - https://github.com/uutils/coreutils/blob/main/util/build-gnu.sh
2. run the gnu testsuite with our impl - https://github.com/uutils/coreutils/blob/main/util/run-gnu-test.sh
3. parse the results and generate the json file - https://github.com/uutils/coreutils/blob/main/util/analyze-gnu-results.py / https://github.com/uutils/coreutils/blob/main/.github/workflows/GnuTests.yml
4. comments are published this way: https://github.com/uutils/coreutils/blob/main/.github/workflows/GnuComment.yml
5. for the graph, every day (or twice), this project https://github.com/uutils/coreutils-tracking/ is going to download the .json file and generate the graphs

hope this helps!

Thanks! I think 1 and 2 or done with this PR. I'll look at the rest over the next week.
