utils/smpp_mirror: use OSMO_STRLCPY_ARRAY, fix -Wstringop-overflow

This patch fixes a warning printed by gcc 14.1.1:

CC smpp_mirror-smpp_mirror.o CCLD smpp_mirror In function 'snprintf', inlined from 'bind_transceiver' at smpp_mirror.c:121:2, inlined from 'smpp_esme_init' at smpp_mirror.c:258:9, inlined from 'main' at smpp_mirror.c:299:7: /usr/include/bits/stdio2.h:54:10: warning: '__builtin___snprintf_chk' specified bound 16 exceeds destination size 9 [-Wstringop-overflow=] 54 | return __builtin___snprintf_chk (__s, __n, __USE_FORTIFY_LEVEL - 1, | ^

Take a chance to replace all snprintf() calls with OSMO_STRLCPY_ARRAY.
