Ensure rsyslog package present

Some images on some platforms (fedora21 on rax) may not have rsyslog
installed.  There is some custom configuration and a restart done
which assumes the presence of rsyslog.  Since many other things might
rely on /var/log/messages just ensure we have rsyslog installed.
