Adjust emulators/wine to use this port instead of wine-mono-devel,
which we just upgraded a few hours ago.
Approved by: dbn (maintainer, pre-approved) 
Sync with the latest upstream release, required for this week's
snapshot of Wine (which will land in emulators/wine-devel soon).

Feature safe: yes
Mono is an Open Source and cross-platform implementation of the .NET
framework. Wine can use a Windows build of Mono to run .NET applications.
