    Introduce MODULES_EXCLUDE
    
    It's sometimes easier to exclude some modules rather than listing all
    possibly needed ones with MODULES_OVERRIDE.
    So for this add MODULES_EXCLUDE which do exactly as one would guess, excludes
    some modules from the build/install.
    
    For example if one wants to exclude all modules which are only present in the
    GENERIC config on amd64 :
    export MODULES_EXCLUDE=$(grep -E '^device' sys/amd64/conf/GENERIC | awk '{print $2}' | tr '\n' ' ')
