dummysmtpd: accept additional kwargs from stdlib smtpd

This was causing extremely mysterious failures because smtpd is
implemented using asynchat, which in turn doesn't appear to do
anything *remotely* helpful if an exception occurs.

# no-check-commit because I'm editing a foo_bar function signature

test-patchbomb-tls.t now passes in Python 3, but only because it
doesn't check message bodies like test-patchbomb.t. test-patchbomb.t
is *full* of doubled headers in the output (eg [0]) which seems like
an odd failure mode.
