Media: Improve handling of non-image files in wp_get_image_mime.

This prevents non-image fileypes from returning a mime type of "application/octet-stream" when `exif_imagetype()` returns `false`.

Props blobfolio.
Fixes #40017.

Merges [40397] to the 4.7 branch.

Built from https://develop.svn.wordpress.org/branches/4.7@40403
