sgsn: Ensure 0-terminated imsi strings (Coverity)

Currently the size argument of strncpy is set to sizeof(mm->imsi) in
some places. If the source IMSI string is too long, the terminating
NUL byte in the static mm->imsi field gets overwritten.

This patch limits the size to sizeof(mm->imsi)-1, so that the last
byte of the buffer (that has been initialized to 0) is not
overwritten.

Fixes: Coverity CID 12065751, 12065754, 1206575
