Simplify wp_die calls

[Presskopp]

In \src\wp-admin\network\sites.php, L. 126 there's

wp_die( __( 'Sorry, you are not allowed to access this page.' ), '', array( 'response' => 403 ) );

This can be simplified to:

wp_die( __( 'Sorry, you are not allowed to access this page.' ), 403 );

Oh, in case I am right with this, there are some more:

functions.php, L. 1225

wp_die( __( 'ERROR: This is not a valid feed template.' ), '', array( 'response' => 404 ) );

ms-load.php, L. 93, 114:

wp_die( __( 'This site is no longer available.' ), '', array( 'response' => 410 ) );

wp_die( __( 'This site has been archived or suspended.' ), '', array( 'response' => 410 ) );

I see that we shouldn't patch things like that just because we can. Feel free to close.

Thanks for the patch, @Presskopp, but yes I don't think this is an essential change.
