Lay down LS localization suppression file on Linux

microsoft/python-language-server#170

In order to better support Linux containers please add the following to Microsoft.Python.LanguageServer.runtimeconfig.json in the LS folder on Linux:

{
  "runtimeOptions": {
    "configProperties": {
      "System.Globalization.Invariant": true
    }
  }
}

Even better if this can be done only in containers so we don't lose potential localization on Linux in general. It is not appropriate for the LS to suppress localization in general (consider Visual Studio, for example).
