'final_name' by default is the profile name, but ask_exec() will change
it for the target profile (which is a null-* profile at this stage)
based on exec mode choice. ask_addhat() will also change it based on the
chosen hat.
Choosing "deny" or "unconfined" will result in an empty final_name and
ignoring these log events.
All other choices set final_name to the full profile name ("foo" for Px,
"foo//bar" for Cx, current profile for ix).
Also fix the order of handling log events - since ask_exec() changes the
hashlog final_name, it has to run first so that ask_addhat() (which
"only" adjusts the hat name in final_name) and handle_hashlog() can work
with the updated profile name.
Finally, update test-libapparmor-test_multi.py to ignore final_name when
checking if hashlog is empty, and fix the call order of ask_exec() etc.
