    Make UnitIdMap a deterministic map
    
    This impacts at least the order in which version macros are
    generated. It's pretty hard to track what kind of nondeterminism
    is benign and this should have no performance impact as the number
    of packages should be relatively small.
    
    Test Plan: ./validate
