Jörg Thalheim 7d8f1572d1 nixos: enable fstrim by default ...

The majority of users these days will install NixOS on SSD/NVME based
storage. Enabling fstrim ensures that the TRIM operation on this type of
storage is run at least once a week. This will improve performance and
life time of said devices. This also works in virtual machines as
formats such as qcow2 or vmdk support TRIM.
Ubuntu has a similar systemd timer also for quite a while enabled by
default.
Enabling this service will not increase the dependency closure as
util-linux is already part of the base system.
In case only filesystems that are not supported by fstrim are used, the
overhead is negelible as fstrim run in less than a second once a week.
