IMPALA-4722: Disable log caching in test_scratch_disk

test_scratch_disk fails sporadically when trying to assert the presence
of log messages. This is probably caused by log caching, since after
such failures the log files do contains the lines in question.

I manually tested this by running the tests repeatedly for 2 days (10k
runs).

To make future diagnosis of similar problems easier, this change also
adds more output to assert_impalad_log_contains().
