gprs_bssgp: Work around gcc-9 claiming "error=stringop-overflow"
gcc-9.2.1 issues the following errror when compiling with -Werror:
In function ‘tl16v_put’,
inlined from ‘tvlv_put’ at ../../include/osmocom/gsm/tlv.h:156:9,
inlined from ‘tvlv_put’ at ../../include/osmocom/gsm/tlv.h:147:24,
inlined from ‘msgb_tvlv_put’ at ../../include/osmocom/gsm/tlv.h:223:9,
inlined from ‘bssgp_tx_paging’ at gprs_bssgp.c:1250:2:
../../include/osmocom/gsm/tlv.h:131:2: error: ‘memcpy’ reading between 128 and 65535 bytes from a region of size 9 [-Werror=stringop-overflow=]
131 | memcpy(buf, val, len);
| ^~~~~~~~~~~~~~~~~~~~~
Unfortunately I've not been able to work around it with some nice GCC
#pragma GCC diagnostic ignored "-Wstringop-overflow"
