Remove obsolete modules that reference GMT::Maq commands.

GMT::Maq no longer exists.

This change would leave twenty-eight allocations with owner of class `Genome::Model::Event::Build::ReferenceAlignment::DeduplicateLibraries::Maq` unable to find said owners.  (A possible solution is to change their owner_class_name to Genome::Model::Event.)  Instantiating events by ID for the abandoned classes should instantiate `Genome::Model::Event::Generic` instead (assuming that feature of Events still works.), so old Workflows would still be viewable.
