hlr.c: Avoid overflow of lu_operation.subscr.imsi
It appears that hlr_subscriber.imsi is 16 buffers in size:
15 chars for IMSI + 1 byte NUL. However, osmo_gsup_message.imsi
is 17 bytes (for whatever reason), so we cannot simply do a strpy()
as this might overflow the hlr_subscriber.imsi field!
TODO: check if weactually ever receive a too-long IMSI in GSUP and
reject that at an earlier time in the code flow.
