replay: do not copy gpgsign-sha256 header

When "git replay" replays a commit it copies the extended headers
across from the original commit. However, if the original commit
was signed we do not want to copy the header associated with the
signature is it wont be valid for the new commit. The code already
knows to avoid coping the "gpgsig" header but does not know to avoid
copying the "gpgsig-sha256" header.  Add that header to the list of
exclusions to match what "git commit --amend" does.
