Rely on crypto module autoloading in init scripts
    
    SECURE_NFS_MODS isn't necessary any more as we'll autoload any crypto
    modules we need, so rpcsec_gss_krb5 is all we need to load.  Even that
    we could autoload as well, but that will require a kernel fix, and to
    support older kernels we should wait till that fix has been in for a
    while.
