emulators/wine: Make the dependency on wine-mono generic

Instead of hard coding the actual version number use a generic
dependency on simply the port. This makes maintenance easier and
reduces the chance for mistakes.

(We have been using this in emulators/wine-devel for some four
months already since 996345a04d856fdc863ddce257b8d98da8074d6c .)
