test(podman): probe lifted e2e exclusions in the tmachine guest (do not merge)

[politerealism]

Summary

Diagnostic draft, not for merge. Lifts 14 entries from podmanE2eFollowUpBinaries so one rootless tmachine e2e-podman run reports how each binary behaves in the Fedora guest. This supports retiring the exclusion list tracked in #3712.

Related Issue

Part of #3712. This PR will be closed after the results are collected.

Changes

• tests/artifacts.nix: remove 14 binaries from podmanE2eFollowUpBinaries. Still excluded: the three gateway-restart binaries (they self-skip without wrapper metadata and would report false passes), provider_token_exchange (needs wrapper-set SPIFFE fixtures), and provider_auto_create / workspace_lifecycle (migrated in test(conformance): migrate general-conformance e2e tests #4246).

Testing

• Not yet run. Results come from the Branch E2E Checks tmachine job for fedora-podman-rootless e2e-podman. The per-test result is in the "Show Podman E2E test result" step.
• Not covered: rootful Podman, arm64, flakiness (single run), and the excluded binaries above.
