    update-alternatives: Fix determinism issue
    
    getVarFlags returns a dict and there is therefore no sort order. This
    means the order of the X_VARDEPS_X variables can change and hence the
    task checksums can change. This can lead to rebuilds of any parts of
    the system using update-alternatives and their dependees. This is a
    particular issue under python v3.
    
    Add in a sort to make the order of the variables deterministic.
