rsyslog: set status for CVE-2015-3243

Details: https://nvd.nist.gov/vuln/detail/CVE-2015-3243

The issue is about file permissions: by default rsyslog creates world-readable
files. In case a log message contains some sensitive information, then that's
exposed to every user on the system.

However the rsyslog.conf file that is shipped with the recipe solves it: it
already sets non-world-readable default permissions on all files, so this
vulnerability is fixed in the default OE recipe.

See also this package in OpenSuse[1], where it is solved the same way.
