Merge pull request #5693 from RosettaCommons/roccomoretti/update_submodules
Update various submodules
The assorted submodules have accumulated additional commits in their master branches versus their state in the main repo. Update the various submodules to their most recent master branch status.
(Submodules for build & PyRosetta build weren't touched -- it's assumed that they're at the state they're supposed to be.)
