[boost/f18] Convert some shell variables into macros

    Convert some shell variables into macros
    
    PYTHON2_VERSION needs to be visible across sections, and it's awkward to
    define it twice.  Just make it a macro.  %global expands once only.
    
    PYTHON3_* technically doesn't need this, but let's be consistent.
