Remove second entry footer from content-page.php

Hi guys, 

Thanks for sharing this sass version of _s. I find it very useful. This is my first pull request so please let me know if I'm doing something wrong. My apologies if I am. 

This is a pull request to remove the old entry footer from content-page.php so that is matches _s. There are currently two "edit" links under pages. I think the second was introduced during a merge conflict about a month ago.

Cheers.
