[apparmor] [patch] profiles: update postfix-common

[Steve Beattie]

Hi,

Attached is a patch that updates postfix-common to take into account
of some multiarch stuff, some chrooting that postfix does, and that
the postfix master process sends signals to all the different utility
processes.

As a followup, I'd like to move postfix-common from program-chunks
directory (and kill the directory), as it is the last remaining
vestigial file there (the rest having been moved out in 2007!),
and place it into the abstractions/ directory, where it would
serve a similar role as the apache2-common abstraction as well as a
dovecot-common abstraction I have in the pipeline.
