Bazel: compare runtime overlap against headless Gerrit WAR

Add a guardrail that fails if the oauth plugin bundles third-party
runtime jars that are already provided by Gerrit.

Use //:headless.war.jars.txt as the comparison manifest instead of
//:release.war.jars.txt.

The release WAR is not the right boundary for this check because it also
includes the packaged core plugins via //plugins:core. Comparing against
that manifest would make this test depend on the full set of core plugin
submodules being present during Bazel analysis.

In CI/CD the plugin is built inside a partial Gerrit clone without
fetching the core plugin submodules. Using the release WAR manifest
would therefore fail analysis before the test can run.

The headless WAR already provides the correct comparison scope for this
guardrail: jars shipped by Gerrit itself, but not jars contributed by
the packaged core plugins. This keeps the overlap check focused on
libraries provided by Gerrit runtime, while avoiding an unnecessary
dependency on core plugin submodules.

The test remains Gerrit-tree-only and is gated via:

  target_compatible_with = in_gerrit_tree_enabled()

so standalone plugin builds continue to report it as SKIPPED.
