Ignore "SANITIZED ... NULL byte(s)" messages.

Newer versions of the amavisd daemon sanitize NULL bytes within the
body of a message for the benefit of Cyrus IMAP. When it does this,
the number of bytes sanitized is logged. This is an informational
message only as far as I can tell, so it's been added to the list of
messages to ignore.
