rustdoc: remove pointless CSS `.rightside { padding-right: 2px }`

This CSS was added in 34bd2b8, as `.since { padding-right: 2px }`, to prevent it from uncomfortably touching the srclink, which were separate floated elements. It was carried forward with 962c0a4 to the new `.rightside`, but its role was replaced with adding " • " between them. All it does now is pushes the element 2px away from the page's right margin.

Removing this rule changes the page layout, but you have to look for it to notice it.
