dmenu_bw: Type password instead of copying it

Auto-typing the password, instead of copying it to the clipboard, is
more secure, since any process can read the contents of the clipboard.
It is also significantly more convenient, avoiding the paste step, and
works in situations where pasting isn't possible (such as into a VM
console).
