db_sms_test: Do not print exact memcmp result

man memcp doesn't define exact values for returned integer, it only
specifices a meaning for the sign of it.
So it happens that different versions/implementations actually return
different values when this test is run, making it fail.
Let's simply drop that info from logs since anyways it's not useful.
