Subject: [PATCH] cadence.py: wine ASIO settings: use safe tempfile

This fixed tempfile path poses a security issue that even might allow
other users on the system to inject arbitrary wine registry settings, if
protect_symlinks and protect_regular kernel protection is not enabled.

Use a proper NamedTemporaryFile to pass the data to regedit to fix this.
