In Bazel 8+, RUNFILES_DIR may not be set during coverage post-processing. This change: - Makes RUNFILES_DIR optional, with fallback to BAZEL_COVERAGE_INTERNAL_RUNFILES_DIR - Derives the bindir from COVERAGE_DIR when runfiles is unavailable - Simplifies the test binary lookup logic

Make sure RUNFILES_DIR also tries BAZEL_COVERAGE_INTERNAL_RUNFILES_DIR. This change ensures that we don't throw a fatal error and exit due to RUNFILES_DIR being empty.
In bazel 8, coverage collection script clears RUNFILES_DIR before calling language specific coverage collectors. The rules_rust collect_coverage tool was panicking because it required RUNFILES_DIR to be set.
