Updated git submodules

Project: releng/builder master c88dfef311c84bef3aabcfcec287a20d223303fe

Removed the version details of nuget and mono-complete

- The bug https://bugzilla.xamarin.com/show_bug.cgi?id=41953
  was resolved, so this is not required anymore.

- I have validated the new nuget is able to download the
  package.
