Subject: [PATCH] [Java.Interop] allow $(TargetFrameworkVersion) to be passed
 in

Context: https://github.com/xamarin/xamarin-android/pull/2105#issuecomment-416582929

To build `Java.Interop.csproj` as `MonoAndroid,v1.0`, we need to set
the following properties:

    <PropertyGroup>
        <TargetFrameworkIdentifier>MonoAndroid</TargetFrameworkIdentifier>
        <TargetFrameworkVersion>v1.0</TargetFrameworkVersion>
        <TargetFrameworkRootPath>$(XAInstallPrefix)xbuild-frameworks</TargetFrameworkRootPath>
    </PropertyGroup>

Currently it looks like `$(TargetFrameworkVersion)` is the only one we
can't modify downstream in `xamarin-android`.
