build error:
In function ‘eal_plugin_add’,
.../lib/librte_eal/common/eal_common_options.c:225:2:
error: ‘strncpy’ output may be truncated copying 4095 bytes from a
string of length 4095 [-Werror=stringop-truncation]
strncpy(solib->name, path, PATH_MAX-1);
strncpy may result a not null-terminated string,
replaced it with strlcpy
