This was added in 2013 with I68594d489ab50ef25d351162b9dcb50ca003c409
to avoid rsyslog trying to open /dev/xconsole, and is no longer
relevant.
To get back to the upstream default, remove the modified file, purge
the package and re-install it. We can remove this shortly after it
has applied to servers.
