[services] Update "WantedBy=" section for tacacs-config.timer. (#11893)

The timer execution may fail if triggered during a config reload
(when the sonic.target is stopped). This might happen in a rare
situation if config reload is executed after reboot in a small
time slot (for 0 to 30 seconds) before the tacacs-config timer
is triggered. To ensure that timer execution will be resumed after
a config reload the WantedBy section of the systemd service is updated
to describe relation to sonic.target.
