scripts/fcsim1-sst: turn off STK & OTA services In the initial unprogrammed state of the cards from Grcard, SST has services 25 through 29 set to allocated and activated. However, these cards appear to not actually support OTA, ENVELOPE commands do nothing (just return SW 9000), and they were never observed issuing any proactive SIM commands, even after a feature-generous TERMINAL PROFILE. Therefore, let's list these STK & OTA services as allocated, but not activated in our FCSIM1 SST.
