Currently, the instrumented binary is sourced from the `TARGET_FILE` environment variable. For wrappers around `rust_test`, this variable points to the wrapper rather than the actual binary, which breaks code coverage. This change: * Introduces the `RULES_RUST_TEST_BINARY_OVERRIDE` environment variable, which wrapper authors can use to supply the path to the original test binary. * Uses the runfiles library to resolve `runfiles_dir` instead of relying solely on the `RUNFILES_DIR` variable.
