Include Kotlin runtime in Java test runner archive

Summary: `BasePerTestCoverageRunListener` is implemented in Kotlin, but `testrunner-bin-fixed` filtered `kotlin/` classes out of the vanilla Java test runner archive. Selective Java coverage therefore failed during listener initialization with `NoClassDefFoundError: kotlin/text/Regex` before producing coverage data. Preserve the Kotlin runtime in the vanilla archive, matching the existing Android runner behavior, and teach the archive guard to allow that namespace while continuing to exactly allowlist other entries.
