Building for desktop shouldn't require a RID

[ericstj]

When I build for desktop I see

f:\cli\latest\sdk\1.0.0-rc4-004530\Sdks\Microsoft.NET.Sdk\build\Microsoft.NET.RuntimeIdentifierInference.targets(49,5): error : RuntimeIdentifier must be set for .NETFramework executables. Consider RuntimeIdentifier=win7-x86 or RuntimeIdentifier=win7-x64.

Why do we force folks to specify a RID? We should be able to restore and build just fine without a RID for desktop. That's the precedent set by NuGet 2. At the very least we should probably be just assuming some RID for desktop if the user hasn't specified one. Forcing it in the project file is busted.

Dupe of dotnet/project-system#1333.

That's fair, but the targets live here so I thought this would be the place to file the issue. https://github.com/dotnet/sdk/blob/master/src/Tasks/Microsoft.NET.Build.Tasks/build/Microsoft.NET.RuntimeIdentifierInference.targets

Both are dupes to another issue in the SDK - #357 :)

Thanks @srivatsn

Ha, and that one is a dup of #396
