Subject: apparmor: Fix network event parsing
References: bnc#665483

The upstream version of AppArmor had network mediation but it was
 removed. There's a compability patch floating around that both openSUSE
 and Ubuntu have applied to their kernels. Unfortunately, one part was
 overlooked. The socket operation event names where changed from the
 socket_ prefixed names they had when AppArmor was out-of-tree and
 utils/SubDomain.pm was never updated to understand them.

This patch adds an operation-type table so that the code can just
 do a optype($operation) call to discover what type of operation a
 particular name refers to. It then uses this in place of the socket_
 checks to decide whether an event is a network operation.

This allows genprof and logprof to work with networking rules again.
