vim: Upgrade 4269 -> 4134

License text underwent changes on how to submit Uganda donations, switch from http
to https urls and an update date change but the license itself is unchanged.

Also, add an entry for the top level license file. This is also the vim license
so LICENSE is unchanged but we should monitor it too.
