Subject: [PATCH] Fix trimming of System.Net.Ping (dotnet/corefx#41180)

It has an ILLinkTrim.xml file that was keeping a type around for testing, but that's apparently keeping the assembly from being trimmed in a published app.

Commit migrated from https://github.com/dotnet/corefx/commit/64c7228b941d1402009c57441a5a8c634d0e6843
