tests: reduce subsurface-test verbosity

Not printing these will drop 7980 lines or roughly 350 kB from the test
logs. Now I don't have scroll through them all, and I don't have to
watch them if I run this test manually.

These prints were useful when developing the test, but we don't need
them printed in CI all the time. Printing the final count should be
enough.
