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".

Test issue2761

  $ hg init

  $ touch to-be-deleted
  $ hg add
  adding to-be-deleted
  $ hg ci -m first
  $ echo a > to-be-deleted
  $ hg ci -m second
  $ rm to-be-deleted
  $ hg diff -r 0

Same issue, different code path

  $ hg up -C
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ touch does-not-exist-in-1
  $ hg add
  adding does-not-exist-in-1
  $ hg ci -m third
  $ rm does-not-exist-in-1
  $ hg diff -r 1
