syslog.conf: correct PID file path in comments.
syslog.conf: correct PID file path in comments.

The syslogd.pid file has moved from /usr/run to /var/run. The comments
in syslog.conf direct the user to restart syslogd using the old PID
file location. This patch updates the comment to match the code.
