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.
