Allow system server read binderfs stats
When receiving the binder transaction errors reported by Android
applications, AMS needs a way to verify that information. Currently
Linux kernel doesn't provide such an API. Use binderfs instead until
kernel binder driver adds that functionality in the future.
Bug: 199336863
Test: send binder calls to frozen apps and check logcat
Test: take bugreport and check binder stats logs
