  perf_tests: Normalize MS counts in EGL init test.
  
  The un-normalized values depend on the number of frames rendered, so
  if we optimize down one time, the other ms values all increase,
  because we are rendering more frames. This generates spurious perf
  alerts from the perf dashboard.
  
  BUG=None
