[apparmor] [PATCH] parser: Preserve techdoc files in the clean target

[intrigeri]

Hi,

note that as far the Debian packaging is concerned, I'll keep building
that file from source: that's the only way to guarantee that we
distribute the source "code" corresponding to the binary artifacts
included in our binary packages. This doesn't conflict with the
proposed patch though, I'll just need to delete the pre-built PDF
found in the upstream tarball before building, to ensure it is indeed
built from scratch :)

Cheers,
