Title: Likes: display below excerpts as well

Before this commit, Likes were only displayed below `the_content`
Sharing buttons, on the other hand, are displayed everywhere:
https://github.com/Automattic/jetpack/blob/2.9.3/modules/sharedaddy/sharing-service.php#L607

Both modules should have the same behaviour in my opinion.
