build system: establish priority levels for CBFS file additions

Add files with fixed positions, then files with alignment requirements
    and finally those that can reside everywhere to prevent the most obvious
    collisions.
    This isn't perfect yet (the "aligned" group may need some additional
    sorting), but should avoid the worst instances ("free floating" files
    allocating space required by fixed location files, for example).
