[pve-devel] [PATCH proxmox] apt: tests: remove output directories before running test

[Fiona Ebner <f.ebner@proxmox.com>]

I blindly assumed that cargo would re-create the TMPDIR before each
test run, but that doesn't seem to be the case and the test_digest
test now fails the second time when running 'cargo test' twice.

So partially revert 9b7c533 ("apt: tests: create temporary test
directories in CARGO_TARGET_TMPDIR") and re-introduce the
remove-before-test logic.

Fixes: 9b7c533 ("apt: tests: create temporary test directories in CARGO_TARGET_TMPDIR")
