dwm-6.4 is supported! but the .diff file is broken

[kigel]

Hello contributers! i really like this patch because i came from Qtile which uses the same logic in the sense of the tagset/workspaces are the same for all monitors, so i thank you for making this patch.

Altough the patch it self still works, the .diff file is broken and i had to manually apply this patch.

so it would be nice if you updated the .diff file for dwm-6.4 :)
