sgsn: fix problem with leading-zero-IMSIs

When the IMSI ACL is maintained via the VTY, users may enter IMSIs
without leading zeros. Especially in test environments, where
MCC=001 and MNC=01 is common, it is likely that someone enters the
corresponding IMSI (001010000000001) without the two zeros at the
beginning.

This patch fixes the problem by sanitizing the IMSI, eventually
missing zeros in the beginning will be automatically added.
