RepoToolset fails on macOS

[natemcmaster]

I'm trying to use repotoolset to compile the dotnet/arcade repo on macOS, and I get the following error

/Users/namc/.nuget/packages/roslyntools.repotoolset/1.0.0-beta-62614-02/tools/RepoLayout.props(37,5): error MSB4185: The function "GetFolderPath" on type "System.Environment" is not available for execution as an MSBuild property function.

It looks like the problem is here:

roslyn-tools/sdks/RepoToolset/tools/RepoLayout.props

Line 37 in 5780611

<NuGetPackageRoot Condition="'$(NuGetPackageRoot)' == '' AND '$(OS)' != 'Windows_NT'">$([System.Environment]::GetFolderPath(SpecialFolder.Personal))\.nuget\packages\</NuGetPackageRoot>

Using: dotnet 2.1.300-preview2-008251, macOS 10.13
