Merge pull request #9271 from @Profpatsch.

Not sure whether this was broken in the first place (8cd6d53) or if it
went broken afterwards (due to the version bump in 04e39bd), but it
isn't included in the store path at current master.

So I've tested the commit and kbd now correctly includes the Neo layout.
