[PATCH] Use python-config to find python include directories



In Ubuntu's current development release, the Python header files have
been split up for multiarch reasons. /usr/include/python2.7/Python.h
includes pyconfig.h, which is in
/usr/include/x86_64-linux-gnu/python2.7/. This causes a build failure
beacuse the architecture specific include directory is not searched by
the audit build system.

This patch uses the python-config tool, normally provided by the Python
development package, to determine include directories and improves the
readability of the Python section of configure.ac by adding appropriate
indentation.
