MINOR: [Dev] Add apt/yum build directories to .gitignore (#46018)

### Rationale for this change

Linux packaging builds copy/create a lot of files that weren't marked as ignored, so they were not deleted by `git clean -Xfd`.

### Are these changes tested?

Manually.

### Are there any user-facing changes?

No.
