change certficate owner to syslog for ubuntu

Hi,

the rsyslog daemon is running as 'syslog' user on ubuntu.

You will get this error:

> Oct  8 12:43:15 example rsyslogd-2068: could not load module '/usr/lib/rsyslog/lmnsd_gtls.so', rsyslog error - 2078 [try http://www.rsyslog.com/e/2068 ]

If the certficate is owned by root because the rsyslogd can't read it.

Tested with Ubuntu 12.04 LTS
