    Fix conditional build of auth_mellon_diagnostics.c
    
    Commit de853e15 introduced using config.h to define optional build
    parameters instead of putting them on the compile command
    line. Unfortunately that broke the compilation of
    auth_mellon_diagostics.c.
    
    We used to have this:
    
    ifdef ENABLE_DIAGNOSTICS
    include "auth_mellon.h"
    
    but the flag ENABLE_DIAGNOSTICS is now defined by including
    auth_mellon.h (which includes config.h) hence it would be impossible
    for the ENABLE_DIAGNOSTICS to be defined during compilation.
    
    The solution is simple, just reverse the order of the two lines such
    that the defines are seen before the #ifdef conditional.
