In facebook#8268, the `db_stress` stdout began containing both the strings "fail" and "error" (case-insensitive). The whitebox crash test failed when stdout contained one or more of those strings. I checked that all other occurrences of "fail" and "error" (case-insensitive) that `db_stress` produces are printed to `stderr`. So this PR separates the handling of `db_stress`'s stdout and stderr, and only fails when one or more of those strings is in stderr. Test Plan: run it; see it succeeds for several runs until encountering a real error ``` $ python3 tools/db_crashtest.py whitebox --simple --random_kill_odd=8887 --max_key=1000000 --value_size_mult=33 ... db_stress: cache/clock_cache.cc:483: bool rocksdb::{anonymous}::ClockCacheShard::Unref(rocksdb::{anonymous}::CacheHandle*, bool, rocksdb::{anonymous}::CleanupContext*): Assertion `CountRefs(flags) > 0' failed. TEST FAILED. Output has 'fail'!!! ```

Summary: In #8268, the `db_stress` stdout began containing both the strings "fail" and "error" (case-insensitive). The whitebox crash test failed upon seeing either of those strings. I checked that all other occurrences of "fail" and "error" (case-insensitive) that `db_stress` produces are printed to `stderr`. So this PR separates the handling of `db_stress`'s stdout and stderr, and only fails when one those bad strings are found in stderr. The downside of this PR is `db_stress`'s original interleaving of stdout/stderr is not preserved in `db_crashtest.py`'s output.
