Test runner doesn't honor --vs-config option when searching for mysqld

[Alex Budovski]

I added some instrumenting code. When it looks for DLLs, it does the right thing (uses sub vs_config_dir), but 'sub find_mysqld' ignores vs-config completely, and finds the first available one! In this case, I asked for the debug configuration, but it found the first available one which was RelWithDebInfo.

Apart from being incorrect, this can also cause crashes due to inconsistency created between modules.
