add OSMO_IMSI_BUF_SIZE

Various places in our code base figure out how many chars they need to safely
store an IMSI. An IMSI can have a checksum digit, which is not reflected by
GSM23003_IMSI_MAX_DIGITS. And we usually need a terminating \0.

Instead of having a magic +2 repeated every so often, rather define
OSMO_IMSI_BUF_SIZE to contain both checksum digit and nul char, and have the
explanatory comment with it here in libosmocore.
