package/apparmor: new package

The various AppArmor utilities are spread in a few sub-directories of
the apparmor source tree. For now, we build only the parser, but we'll
soon introduce support for a few other utilities, so we prepare the
package to be able to build more than just the parser, hence the
slightly convoluted build and install commands, and the use of the
APPARMOR_TOOLS and APPARMOR_MAKE_OPTS variables, which will come handy
in the following commits.

We must ensure the version matches that of libapparmor, but there is not
much we can do to enforce that, so as we do for various other packages,
we just add a comment to that effect.
