selftests/damon/wss_estimation: deduplicate failed samples output

When the test fails, it shows whole sampled working set size measurements.
The purpose is showing the distribution of the measured values, to let
the tester know if it was just intermittent failure.  Multiple same values
on the output are therefore unnecessary.  It was not a big deal since the
test was failing only once in the past.  But the test can now fail
multiple times with increased working set size, until it passes or the
working set size reaches a limit.  Hence the noisy output can be quite
long and annoying.  Print only the deduplicated distribution information.
