Update LBANN generator and bug fix (#9906)

* Added a package for the MDAnalysis toolkit.

* Added Ninja as the generator for LBANN, Hydrogen, and Aluminum.  Also
fixed a bug in how the Conduit variant is included in LBANN.  Added
new versions for Hydrogen and LBANN.

* Updated lbann package so that the CMAKE parameters are set when the
variant is on and off.
