extdiff: allow modifications in subrepos to be copied back

This check was a legacy bit from when the file data was being fetched manually
with 'ctx[wfn]', but archive() does that now.  49966b5ab16f seems to indicate
that this avoided a problem where a merge adds a file to another branch, and
that test still passes.

Unfortunately, I don't see a way to create a test that modifies the file in the
temporary directory before the command exits.

I wonder if the os.lstat() call needs to be wrapped in an exception handler for
the case where archive didn't create a file because the file didn't exist in
that revision.  But I wasn't able to trigger a problem without it on a real
repository.

  $ hg init

  $ echo 123 > a
  $ hg add a
  $ hg commit -m "first" a

  $ mkdir sub
  $ echo 321 > sub/b
  $ hg add sub/b
  $ hg commit -m "second" sub/b

  $ cat sub/b
  321

  $ hg co 0
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved

  $ cat sub/b 2>/dev/null || echo "sub/b not present"
  sub/b not present

  $ test -d sub || echo "sub not present"
  sub not present
