Concept ACK Thanks for doing this: faster fuzzing is better fuzzing. |

I couldn't verify my claim that this speeds up fuzzing, but at least I am no longer running out of disk space, so I think it is still required. |

Summary: This will allow for the scheduler to be destructed even for tests that only use the `BasicTestingSetup`. This fixes a TSAN lock order inversion issue when running the `reverselock_tests` and the `scheduler_tests` together. Extracted from core [[bitcoin/bitcoin#18571 | PR18571]]. Test Plan: ./src/test/test_bitcoin -t reverselock_tests,scheduler_tests ninja check Reviewers: #bitcoin_abc, deadalnix, jasonbcox Reviewed By: #bitcoin_abc, deadalnix, jasonbcox Differential Revision: https://reviews.bitcoinabc.org/D6766

Summary:
```
There are several issues with writing to a debug log file when fuzzing:
Disk access is slow, but fuzzing should be fast (Note: I could not
verify this claim with data)
Disks have a limited size and will eventually run out of space, but
fuzzing should run continuous
Fix both issues by disabling the debug log file for fuzz tests
```
Backport of core [[bitcoin/bitcoin#18571 | PR18571]].
Depends on D8636.
Test Plan:
ninja all check
ninja bitcoin-fuzzers
./test/fuzz/test_runner.py <path_to_corpus>
