Fixed the format problem of the generated .timer file.

[choems]

I noticed two problems.
First, the format of OnCalendar. According to the manual page of systemd.time(7), it should be like this.


And this is the current format: "OnCalendar=#{@Cron[:Weekday]}-*-#{@Cron[:Month]}-#{@Cron[:Day]} #{hours}:#{minutes}:00"

The second problem is the "Unit=" field under [Timer]. It should contain the service suffix, that is, .service, otherwise you will get message like this: /home/choems/.config/systemd/user/homebrew.logrotate.timer:8: Unit type not valid, ignoring: homebrew.logrotate
