nixos/zfs: make zpool-trim timer persistent
If the machine is powered off when the zpool-trim timer is supposed to
trigger (usually around midnight) then the timer will be skipped
outright in favor of the next instance.
For desktop systems which are usually powered off at this time, zpool
trimming will never be run which can degrade SSD performance.
By marking the timer as `Persistent = yes` we ensure that it will run at
the first possible opportunity after the trigger date is reached.
