patchbomb: do not assume the presence of angle brackets around msg-id
RFC 5322 states:
"Semantically, the angle bracket characters are not part of the
msg-id; the msg-id is what is contained between the two angle bracket
characters."
Hence it should be correct to pass a message Id with no angle brackets
to --in-reply-to. Adding them if missing.
