tests: configure fsmonitor.mode=paranoid always if fsmonitor is used

This forces fsmonitor extension execute "paranoid" code path.

Strict speaking, we should make fsmonitor-run-tests.py accept own
specific options, but there is no code path, which is disabled in
"paranoid" mode, at least now. Therefore, this solution seems
reasonable enough.
