Parse just headers when extracting message ID from stdin mbox

When the mbox and am subcommands grab a message ID from the mbox
on stdin, they call message_from_bytes(), which in turn calls
BytesParser().parsebytes(s).

parsebytes() has a headersonly parameter that can be used to tell it
to stop parsing after reading the headers.  The headers are all that's
needed here, so use BytesParser directly and set headersonly.
