feat(24.04): add finalrd and add bins slice to libc-bin

[Meulengracht]

Proposed changes

Finalrd is needed by Ubuntu Core - added the package and extended libc-bin by adding the binaries it carries. Those are needed not only by the finalrd script (which invokes ldconfig), but also by our hooks in ubuntu core.

I added a test for finalrd, but as expected it will fail, so we just ensure it fails in the way we expect.

This is a difficult slice to test. I'll ask around our team and see if anyone has an additional strategy. Other than that I only have the one question below.

Thanks! :)

Since this is a shell script should we add dash_bins for the shell and base-files_bin for /bin?

you probably don't need the entire coreutils, so I suggest creating a new coreutils slice(s) with just the bins you need for this.

We need tests for this
