package/libapparmor: new package

The layout of the package is not amenable to building both the library
and the utilities at once, so this package will only install the
library.

The other apparmor-related tools however will almost all want to always
link with the static library (it's hard-coded in their Makefiles, like:
AALIB = -Wl,-Bstatic -lapparmor -Wl,-Bdynamic -lpthread), so we also
force the build of the static library.

The kernel headers 3.16 at least are required, for CAP_AUDIT_READ.

We need to force the C standard to gnu99, otherwise:

  - autoconf uses wchar_t in C99 test, so considers it to be missing
    on toolchains without wchar, but wchar is not otherwise needed for
    libapparmor;

  - c99 is not enough, otherwise the build fails with errors like:
        kernel.c:503:15: error: expected declaration specifiers or ‘...’ before ‘(’ token
         extern typeof((__change_hat)) __old_change_hat __attribute__((alias ("__change_hat")));
                       ^

+         AppArmor is an effective and easy-to-use Linux application
+         security system. AppArmor proactively protects the operating
+         system and applications from external or internal threats,
+         even zero-day attacks, by enforcing good behavior and
+         preventing even unknown application flaws from being
+         exploited.
+
+         This package installs only the library.
