[apparmor] [PATCH v3 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 called cov-int. 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
apparmor-<SNAPSHOT_VERSION>-cov-int.tar.gz, and is suitable for
uploading to scan.coverity.com.

* Changes since v2.1:
  - Get rid of the coverity target-specific IGNORED_DIRS and DIRS make
    variables and put the logic directly into the foreach loop.
