[Bug 45271] Silence winemenubuilder.exe error if it is disabled by user

https://bugs.winehq.org/show_bug.cgi?id=45271

--- Comment #1 from Rosanne DiMesio  ---
The info that winemenubuilder has been disabled is useful to those of us
troubleshooting problems on the forum, and users don't always think to mention
it, or sometimes even know themselves (PlayOnLinux does it automatically).

I wouldn't want to see the message entirely suppressed, but perhaps the wording
should be changed to something like "winemenubuilder has been disabled."
