swaylock: Submit password on Ctrl-D

Browse Source 
Ctrl-D functions as EOF in most cases on the terminal. login(1) & many other
programs check the password on EOF, same as Enter. To make behavior consistent,
have swaylock submit the password on Ctrl-D.

This commit moves the handling for Enter into its own static function, which is
now also called on Ctrl-D.
