Work around bogus gcc-8.2 array-bounds warning/error

gcc-8.2 is printing the following warning, which is an error
when used -Werror like our --enable-werror:

In file included from gprs_bssgp.c:34:
In function ‘tl16v_put’,
    inlined from ‘tvlv_put.part.3’ at ../../include/osmocom/gsm/tlv.h:156:9,
    inlined from ‘tvlv_put’ at ../../include/osmocom/gsm/tlv.h:147:24,

../../include/osmocom/gsm/tlv.h:131:2: error: ‘memcpy’ forming offset [12, 130] is out of the bounds [0, 11] of object ‘mi’ with type ‘uint8_t[11]’ {aka ‘unsigned char[11]’} [-Werror=array-bounds]
  memcpy(buf, val, len);

Where "130" seems to be the maximum value of uint8_t, shifted right one +
2.  But even as we use strnlen() with "16" as maximum upper bound, gcc
still believes there's a way that the return value of gsm48_generate_mid_from_imsi()
could be 130.  In fact, even the newly-added OSMO_ASSERT() inside
gsm48_generate_mid() doesn't help and gcc still insists there is a problem :(
