filemerge: stop passing around 3 unused `None` values in `files` argument

Since 67cfffbfb6a0 (filemerge: eliminate most uses of tempfiles,
2017-08-31), we have used only the last entry in the `files` tuple
that gets passed around to various functions. That commit said
"Emphasize that they're unused so we can more easily remove them
later.". It's now "later".
