aa-genprof should give the pathname to the generated profile

maslen on IRC suggested that aa-genprof should also print the pathname to the generated file; I suspect this should be a common feature of writing the profiles, whether via aa-genprof, aa-logprof, aa-autodep, etc., since the next usual step is to edit the profile and inspect or modify it, having the filename handy for copy-and-paste or education makes good sense.

Thanks
