tests: Fix spurious failures in stats-dump.t test
The test fails to grep and find queue_size, in a brick stats
dump, having succesfully found aggr.* values in the same.
The troubleshot is that, the writer thread in io-stats, that
dumps this in a particular interval, truncates the file just before
the grep attempts to read the contents, and hence the failure.
The fix is to stop the dumper thread, and then wait for a couple
of seconds and then check the output, so that the thread writer
does not interfere with the test.
Fixes: bz#1615582
