nft: Avoid buffer size warnings copying iface names
The call to strncpy() is actually not needed: source buffer is only
IFNAMSIZ bytes large and guaranteed to be null-terminated. Use this to
avoid compiler warnings due to size parameter matching the destination
buffer size by performing the copy using (dumb) memcpy() instead.
