[apparmor] [patch] - performance again... small changes

[Peter Maloney]

In my testing, these small changes affected the "aa-logprof" measured
from the running of the command until the interactive options appear,
made it take 10-17% less time.

Here's a short test that takes 17% less time (I think this log was
around 50 MB). I also did a much huger log which was also around 13%.
And then after my previous patches, I tested again and got 10%. I'm not
sure if it affects more than the start up.


before:
    real    0m9.704s
    user    0m9.474s
    sys     0m0.224s

    real    0m9.949s
    user    0m9.770s
    sys     0m0.179s
   
    real    0m9.951s
    user    0m9.763s
    sys     0m0.187s
   
    real    0m9.848s
    user    0m9.650s
    sys     0m0.198s
   
after:
    real    0m8.075s
    user    0m7.954s
    sys     0m0.122s

    real    0m8.310s
    user    0m8.196s
    sys     0m0.114s

    real    0m8.260s
    user    0m8.075s
    sys     0m0.173s

    real    0m8.109s
    user    0m7.958s
    sys     0m0.151s

scale=10
o=(9.484+9.77+9.76+9.65)
p1=(7.954+8.196+8.075+7.958)
p1/o
.8323763707


I was going to test the 2 separately to see if p1b is necessary, but
cboltz seems to like its readability and prefers it anyway, so here it is.
