Add weekly and monthly systemd timers for trimming

Browse Source 
On machines using systemd, trim timers can be enabled on a per-pool
basis. Weekly and monthly timer units are provided. Timers can be
enabled as follows:

systemctl enable zfs-trim-weekly@rpool.timer --now
systemctl enable zfs-trim-monthly@datapool.timer --now

Each timer will pull in zfs-trim@${poolname}.service, which is not
schedule-specific.

The manpage zpool-trim has been updated accordingly.
