[dpdk-dev] [PATCH 2/2] eal: fix build with gcc 9.0

[Ferruh Yigit]

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 rte_strscpy

Fixes: fa9cdc6f8410 ("eal: move plugin loading from linuxapp to common")
