[apparmor] [patch] add pkg-config support to libapparmor

[Steve Beattie]

Given that we want to do more apparmor things in user space (dbus
mediation, file picker, etc.), making it easier for other source bases
to detect the presence of libapparmor would be beneficial. This patch
adds pkg-config support to the build infrastructure for libapparmor.

(This code is mostly monkey-patched mimicry; people who actually know
what they're doing with pkg-config are encouraged to comment.)
