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.
