checkpatch: update signature "might be better as" warning
email header lines can look like signature tags. It's valid to have multiple email recipients on a single line but not valid to have multiple signatures on a single line. Validate signatures only when not in the email headers. Clear the $in_commit_log flag when the patch filename appears. Add '-' to the valid chars in a message header for headers like "Message-Id:" and "In-Reply-To:".
