[apparmor] [patch] update postfix-common abstraction

[Steve Beattie]

Update the postfix-common abstraction to cope with signal and unix
socket mediation, update the access to the sasl library locations
in a multiarch compliant way, and allow access to limited bits
of the filesystem paths under which postfix chroots itself to
(/var/spool/postfix/ on Ubuntu).

Nominated for trunk and 2.9.
