selftests: Fix loss of test output in run_kselftests.sh
Commit fbcab13d2e25 ("selftests: silence test output by default") changed the run_tests logic as well as the logic to generate run_kselftests.sh to redirect test output away from the console. As discussed on the list and at kernel summit, this is not a desirable default as it means in order to debug a failure the console output is not sufficient, you also need access to the test machine to get the full test logs. Additionally it's impolite to write directly to /tmp/$TEST_NAME on shared systems. The change to the run_tests logic was reverted in commit a323335e62cc ("selftests: lib.mk: print individual test results to console by default"), and instead a summary option was added so that quiet output could be requested. However the change to run_kselftests.sh was left as-is. This commit applies the same logic to the run_kselftests.sh code, ie. the script now takes a "--summary" option which suppresses the output, but shows all output by default. Additionally instead of writing to /tmp/$TEST_NAME the output is redirected to the directory where the generated test script is located.
