In Ie5ec06152c418c4aa1b620b3d0a904cc9517e5d0 we merged two search
icons. On retrospect, these icons were not the same - one was bigger
than the other.
(see https://phabricator.wikimedia.org/T199000#4501790)
This change replaces the icon with the correct one.

We already make use of the images 'name' key inside
skins.minerva.content.styles.images to define the full
CSS selector. We can use this approach to ship a single version of
the magnifying glass icon, rather than having 2 defined in both
skins.minerva.base.styles and skins.minerva.icons.images
