            Log:
            test if logwatch scripts can check files in /run/netns

Recent logwatch + selinux-policy testing revealed that SELinux
prevents one of the logwatch scripts from checking files labeled
nsfs_t located under /run/netns directory. The TC reproduces the
situation.

In order to support the 'df' command functionality (executed by
one of the scripts, syscall = newfstatat), I believe that SELinux
policy should allow this access. The TC looks for appropriate
policy rules and file context patterns.

The TC covers RHEL-160896 and RHEL-160897.
