Fix linked_list-test flakiness

A recent patch changed this test to do a snapshot scan at the end
which is now failing with a timeout. That patch looped this test
a bunch but, apparently, jenkins is even more stressful than
--stress_cpu_threads=4. I re-looped the test with --stress_cpu_theads=8
and observed 8/1000 failures.

The fix is to increase the timeout. After I did that I looped the
tests again and 1000/1000 passed.

Config:
KUDU_ALLOW_SLOW_TESTS=1 ../../build-support/dist_test.py loop -n 1000 \
bin/linked_list-test --stress_cpu_threads=8 --gtest_filter=*TestLoadAndVerify*

Results:
