Subject: [PATCH] test: Scale feature_dbcrash.py timeout with factor

This allows to run the test under valgrind:

./bld-cmake/test/functional/feature_dbcrash.py --timeout-factor=10 --valgrind

For testing, the same test can be run multiple times in parallel:

./bld-cmake/test/functional/test_runner.py -j 10 $( printf 'feature_dbcrash.py %.0s' {1..10} )  --timeout-factor=10 --valgrind

(Running the test under valgrind may take several hours!)

I found that before this commit, 9 out of the 10 runs failed via:

```

```

With this commit, all 10 runs passed.
