Summary:
Generating megabytes of successful test output has caused
issues / inconveniences for CI and internal sandcastle runs. This
changes their configuration to only print output from failed tests.
(Successful test output is still available in files under t/.)
This likewise changes default behavior of parallel `make check` as
a quick team poll showed interest in that.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/9188
Test Plan:
Seed some test failures and observe
* `make -j24 check` (new behavior)
* `PRINT_PARALLEL_OUTPUTS=1 make -j24 check` (old CI behavior)
* `QUIET_PARALLEL_TESTS=1 make -j24 check` (old manual run behavior)
