96df4b36f6 Workaround signedness bugs in system NLMSG_OK reported by -Wsign-compare 
Introduce a replacement for NLMSG_OK provided by <linux/netlink.h> since

* netlink.h: Include <stdbool.h>.
(is_nlmsg_ok): New static inline function.
* socketutils.c (receive_responses): Use it instead of NLMSG_OK.
* tests/netlink_inet_diag.c (check_responses): Likewise.
* tests/netlink_netlink_diag.c (check_responses): Likewise.
* tests/netlink_unix_diag.c (check_responses): Likewise.

Closes: https://github.com/strace/strace/issues/79
