When host gcc uses _FORTIFY_SOURCE=2 by default, tools/firmware-utils

In file included from /usr/include/string.h:658:0,
from src/imagetag.c:12:

inlined from 'tagfile' at src/imagetag.c:369:11:
/usr/include/bits/string3.h:123:3: error: call to __builtin___strncpy_chk will
always overflow destination buffer
