Jure Varlec 44438e0dcd nixos/fstrim: fix overriding the timer interval
The OnCalendar systemd setting is additive. To clear the setting defined
by the pre-existing unit file, it has to be set first to an empty
string, then to the desired value.

How often we run fstrim. For most desktop and server systems
a sufficient trimming frequency is once a week.
The format is described in
