ci: tests/podman: exclude ever failing test case

[kolyshkin]

The test case named

podman build and remove basic alpine with TMPDIR as relative

always fails here because we're running it inside docker using overlayfs, and TMPDIR="." set by test results in overlay upperdir being on overlayfs. Since nested overlayfs is not supported, the mount fails:

overlay: filesystem on ..../upper not supported as upperdir

Since the test case is always failing and is not really testing any specific crun aspect, let's skip it.

This should bring Test (podman) back to green.

Fixes: #1999

Summary of Changes

Hello @kolyshkin, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request addresses a persistent CI failure by excluding a specific Podman build test case. The test, which involves building an Alpine image with a relative temporary directory, consistently fails when run inside a Docker container due to an incompatibility with nested OverlayFS. By skipping this non-critical test for crun aspects, the PR aims to restore stability to the Podman test suite.

Highlights

• Test Exclusion: The test case named "podman build and remove basic alpine with TMPDIR as relative" has been added to the skip list in the run-tests.sh script.
• Reason for Exclusion: This specific test consistently fails in the Docker-in-Docker environment due to issues with nested OverlayFS, where TMPDIR="." results in an overlay upperdir being on an overlayfs, which is not supported.
• CI Stability: Skipping this test is expected to resolve the continuous failures in the Test (podman) suite, bringing it back to a green state.

Code Review

This pull request correctly excludes a persistently failing test case by adding it to the --skip list in the ginkgo command. The change is justified by the environment limitations explained in the description. I've added one minor suggestion to correct a potential typo in an issue number reference within a comment.
