fix(test): package datarouter docker config at opt/datarouter/etc

[antonkri]

What

Packages the datarouter component-test config so it lands at opt/datarouter/etc/* regardless of whether score_logging is built as the root module or consumed as an external Bazel dependency.

Why

The datarouter component tests (//score/test/component/datarouter:test_datarouter_filters, test_mw_log, test_mw_log_filters, …) pass in this repo's own component_tests.yml, but fail when score_logging is pulled in as an external dependency (e.g. in eclipse-score/reference_integration).

The datarouter runs with cwd=/opt/datarouter and opens ./etc/log-channels.json. In the external build the config files were packaged at:

opt/datarouter/external/score_logging+/score/test/component/datarouter/etc/log-channels.json   ❌

instead of:

opt/datarouter/etc/log-channels.json   ✅

So ReadStaticDlt fails → DltLogServer is nullptr → "static config is not available, interrupt work" → the unix socket never opens → every test times out with Datarouter not ready within 10.0s.

Root cause

score/test/component/BUILD's _datarouter_conf_pkg used:

pkg_tar(
    ...
    package_dir = "opt/datarouter",
    strip_prefix = "/score/test/component/datarouter",
)

A leading-slash strip_prefix is repo-root-relative and only matches when logging is the root module. When logging is consumed externally the file path is prefixed with external/score_logging+/, the strip matches nothing, and the whole prefix survives under package_dir.

The fix

Package the config via a package-relative pkg_files (datarouter_docker_config_pkg) using strip_prefix.from_pkg(), mirroring the existing QNX datarouter_config_pkg. This resolves to opt/datarouter/etc/* for both root and external consumption.

Downstream

reference_integration currently carries this as a local patch (eclipse-score/reference_integration#387). Once this lands and logging is bumped there, that patch can be dropped.
