Title: specify src and dest for grunt concat consistently

The rest of the Gruntfile uses this simplified way of setting `src` and
`dest` files. So should the `concat` task.

Listing `src` and `dest` separately also makes it unclear how developers
could have multiple sets of files to concatenate.

If my previous PR #1100 is accepted, then there's no need for this.
