System.TypeInitializationException during expression evaluation

[caslan]

This failure stack is the top most non fatal error we are encountering in the debugger. It should have something to do with OpenSSL dependency on OSX but we need to investigate further to see if this is an issue external to debugger or not:

This issue is also tracked with dotnet/roslyn#12681

This is still our top error hit. Lets see if we can fix this for 1.6. My thought is, on OSX, disable the installation of the debugger unless we find openssl.

NOTE: This work around will go away once the debugger is running on https://github.com/dotnet/corefx/issues/9394
