[Bug 47316] Mono/gecko installers should installer after a timeout period

https://bugs.winehq.org/show_bug.cgi?id=47316

--- Comment #2 from Matteo Bruni  ---
Isn't it easier to put the installation files where they are looked for instead
of having to rely on the downloader? E.g. for local wine builds, put the
wine-mono installers under ../mono and gecko ones under ../gecko. If you have
multiple prefixes you probably even want to use the new shared install thing
for mono.
