Read IMSI using SIM I/O for CSIM/RUIM

Use Sim I/O command to read the EF_IMSIM to retrieve the IMSI
from the card, rather than using CommandsInterface.getIMSIForApp.
When both SIM and RUIM app exists, we cannot specify the
application for which we should retrieve the IMSI using the getIMSI
API, since SIM and RUIM have no AID.
