logrotate systemd timer should run hourly rather than daily

Logrotate supports "hourly rotation, however the Ubuntu logrotate systemd Timer runs "daily" - so "hourly" logrotate jobs are still only run daily.

Updating /etc/systemd/system/timers.target.wants/logrotate.timer:
...
[Timer]
OnCalendar=hourly
...

should allow "logrotate hourly" to work as expected.

See related comment at https://github.com/logrotate/logrotate/issues/249#issuecomment-485829363
"The tricky part is that one needs to change the default cron hook
(or systemd timer) to make hourly actually work as expected."

Thanks!
