Attempt to run error_prone_android_framework_test as unit tests

* unclear why the test mapping file is not running with host:true since
it's a java_test_host
* See go/a-unit-tests for full details

The test will continue to be part of presubmit but running as part of
the unit tests suite instead of TEST_MAPPING.
For unit tests, explicit test_mapping declaration isn't needed to run.
