cards: also program EF.AD under ADF.USIM

Browse Source 
DF.GSM and ADF.USIM have an EF.AD with nearly the same contents. Usually
there is one file physically present and the other is just a link.
Apparantly this is not always the case for sysmo-ismi-sja2 cards, so
lets program EF.AD in both locations.
