make Postfix bounce detection work with newer postfix

[jhenstridge]

Mailman does not recognise bounce messages from newer
versions of Postfix. The content-type header on bounce
messages looks like this:

Content-Type: multipart/report;
report-type=delivery-status;
        boundary="2892E4C0CF.1042189077/quoll.daa.com.au"

Mailman only looks for bounce messages with type
multipart/mixed, so skips them.

The simple solution is to check for both content types
(which should allow mailman to continue to work with
old postfixes.

The attached patch is against 2.0.x (haven't upgraded
to MM2.1 yet), but the code is almost identical for 2.1
so the patch should be easy to apply.

Hmm. It seems to have lost the attachment

Not sure if this code is applicable to MM2.1. I guess the
generic DSN bounce detection handles it.

If there is another MM2.0.x bug fix release, it may be nice
to apply.
