gcc 8.3.1 has a compile error due to the warning -Wstringop-truncation

[jhe33]

in file apps/vhost/vhost_user.c, line 36 and 57, the following is the code:

strncpy(un.sun_path, path, sizeof(un.sun_path));

could someone change the strncpy to memcpy to avoid the compile error or add some gcc pragmas, like:

#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Wstringop-truncation"
strncpy(d, s, 32);
#pragma GCC diagnostic pop
