Feature request from developer, support setting uid in Android.bp.

Bug:113359343

Test: source build/envsetup.sh ; lunch
    vim platform_testing/tests/example/native/Android.bp
    add
    test_options: {
        run_test_as: "1234",
    },
    in cc_test
    make hello_world_test
    cat out/target/product/xxxx/testcases/hello_world_test/hello_world_test.config
    Will see  <option name="run-test-as" value="1234" />
    below <test class="com.android.tradefed.testtype.GTest" >
