modules/sendsms: gate the unit with a file

To prevent the unit to be triggered multiple times if the host has
already rebooted, we create a gate file when we're done running, and
before running, we check if the file exists.

Enable the service on tahoe.

Don't restart the unit when its definition has changed.
