[apparmor] [PATCH v2 4/5] Makefile: Add coverity target

[Tyler Hicks]

Add a target that uses cov-build, which must be found in $PATH, to
generate an intermediate Coverity directory. The intermediate Coverity
directory will be based on a clean snapshot of the last commit in the
bzr tree. Finally, the intermediate directory is converted to a
compressed tarball, stored in
coverity/apparmor-<SNAPSHOT_VERSION>-cov-int.tar.gz, that is suitable
for uploading to scan.coverity.com.
