rsyslog: fix configuration file for logrotate

The logrotate.rsyslog file uses 'cat /var/run/rsyslogd.pid' to
determine the pid of rsyslogd daemon. This is incorrect, because
rsyslogd may start in a way that does not create rsyslog.pid file.

Failing to send HUP signal to rsyslogd daemon will result in
unexpected behaviour. e.g. rsyslogd is writing to /var/log/messages-xxxx
instead of /var/log/messages.

We should really use pkill to send HUP signal to rsyslogd to ensure
correct behaviour.
