Subject: [PATCH] fix CI: skip prereq check for mock backend, add bash to
 opensuse

- Add KARAPACE_SKIP_PREREQS=1 env var check to skip runtime prerequisite
  checks (user namespaces, fuse-overlayfs) when testing with mock backend
- Set KARAPACE_SKIP_PREREQS=1 in CLI integration test helper
- Add bash to opensuse/tumbleweed container deps (required by
  dtolnay/rust-toolchain action)
