[apparmor] [patch] libapparmor - use python-config if it exists when configuring

[Steve Beattie]

Author: Dmitrijs Ledkovs <dmitrij.ledkov at ubuntu.com>

This patch modifies the libapparmor macro for python to use
python-config if it exists to determine what CPPFLAGS and LDFLAGS to
use when building the python swig libraries. Without this addition,
python detection fails on ubuntu 13.04. I've confirmed that with this
patch applied, the python libraries still build successfully on older
releases as well (as far back as ubuntu 11.10).
