.NET Core macOS installer is allowed to install on unsupported OS versions

[powellcj12]

Steps to reproduce

1. Download .NET Core installer on a Mac running 10.10
2. Attempt to install it

Expected behavior

Installation fails because .NET Core requires 10.11+ (and .NET Core 2 requires 10.12+)

Actual behavior

Installation succeeds. When using .NET Core 2 installer on 10.10, you get a crash from the post install script that runs.

Some discussion about this in dotnet/core#640 because apparently things worked with .NET Core 1 on 10.10, but now dotnet requires clock_gettime which is only on 10.12 (as mentioned in #8256, and also dotnet/coreclr#10337).

Not clear to me exactly how the installer gets packaged, but it looks like it should only be getting packed for 10.12? See here.

1. I have 10.11.6 and glad I found this quickly enough with nightly build (2.0.0-preview2-25319-02)
2. dang! I guess I better finally move to sierra! :)

I also experienced this. I'm on 10.11.6 as well. The problem is that my regular 1.0 install is now broken, when I try to invoke the dotnet command I get this error:

dyld: lazy symbol binding failed: Symbol not found: _clock_gettime
  Referenced from: /usr/local/share/dotnet/shared/Microsoft.NETCore.App/2.0.0-preview1

Any idea how to remove the preview completely?
