PlatformNotSupportedException when reading ProcessorAffinity on non-Windows platforms

[Ky7m]

InProcessExecutor throws an exception on non-Windows platforms (target framework: netcoreapp1.1). Specifically, it throws an error when try to get ProcessorAffinity InProcessExecutor.cs#L95:

var oldAffinity = process.ProcessorAffinity;

exception:

Unhandled Exception: System.PlatformNotSupportedException: Processor affinity for processes or threads is not supported on this platform.

I found similar issue #298, but it is closed.

Hey @Ky7m, thanks for the report, should be fixed now.

You can check it in BenchmarkDotNet 0.10.8.226 (https://ci.appveyor.com/project/dotnetfoundation/benchmarkdotnet/build/0.10.8.226) from our appveyor feed (see http://benchmarkdotnet.org/Guides/NuGet.htm#nightly)

Thank you @AndreyAkinshin for prompt response and quick fix. I have verified with new source and issue is gone now.
Also it was much needed to continue work on #426 . Thanks again!
