checkpatch: allow space leading blank lines in email headers

Allow a leading space and otherwise blank link in the email headers as it can be a line wrapped Spamassassin multiple line string or any other valid rfc 2822/5322 email header. The line with space causes checkpatch to erroneously think that it's in the content body, as opposed to headers and thus flag a mail header as an unwrapped long comment line.
