dpdk.spec: Do not avoid array-bounds warning by patching the sources
    
    By changing the array size to work around a spurious warning from gcc,
    we run the risk of breaking future code which may rely on the array's
    size (using, ex: sizeof). Since this array-bounds failure is the product
    of gcc-5.x, and not actually an error here, it can safely be ignored.
    
    We need to keep the -Wformat warning, however, because that will trigger
    build errors in some of the PMD builds.
