fcsim1-mkprov: revert OTA key addition
It appears that GrcardSIM2 cards (which is what we got for FCSIM1)
do not support OTA after all, contrary to what we were previously
led to believe by some tech support emails from Grcard - apparently
those support emails and OTA descriptions referred to some other
card model(s).
