ci(free-disk-space): remove more tools and fix warnings

With this PR I remove more space and improve the free-disk-space-linux script.
If you prefer me to split this PR into multiple ones, let me know.

Discussed in [#t-infra > some jobs running out of disk space](https://rust-lang.zulipchat.com/#narrow/channel/242791-t-infra/topic/some.20jobs.20running.20out.20of.20disk.20space/with/591666099)

## Test

I tested this change in marcoieni/actions-test@196ce70. As you can see the workflows run without warnings, which ensures that we can remove all the space possible from the arm runners.

I also tested this change in this repository, by commenting out the mechanism to skip disk cleanup in case there is sufficient available disk space. ( see rust-lang@86529fb )
If I don't comment out the code, it can happen that the CI skips the code I edited because there's enough disk space in the runners that this CI is running.

Here's the change of that commit:

```
# sufficientSpaceEarlyExit
# checkAlternative
```
