aa-logprof should propose profile flags

Follow-up for https://bugzilla.opensuse.org/show_bug.cgi?id=918787

If aa-logprof finds a log line like

type=AVC msg=audit(1424425690.883:716630): apparmor="ALLOWED" operation="file_mmap" info="Failed name lookup - disconnected path" error=-13 profile="/usr/sbin/httpd2-prefork//null-4172" name="var/run/nscd/passwd" pid=25333 comm="id" requested_mask="r" denied_mask="r" fsuid=1002 ouid=0

it should propose to add the "attach_disconnected" flag to the profile.

Note: aa-logprof currently ignores such log events in logparser.py to avoid a crash.
