Updates jank metrics in statsd to include uid.

We need the uid to easily know which app to blame for producing the
frame with excessively long render time. Also updates the errors so
it's more obvious if the error is in parsing versus the other checks.

Test: Test that statsd builds and verified CTS test still passes.
