emacs: limit search for attachment to stop at first mime-part

This commit changes the behaviour of notmuch-mua-attachment-check
so that it stops searching for notmuch-mua-attachment-regexp when a
new mime-part is reached.  This avoids false warnings when matching
words occur inside forwarded messages.
