[PATCH] xshared.h - include sys/time.h to fix lack of struct timeval declaration

[Maciej Żenczykowski <zenczykowski@xxxxxxxxx>]

From: Maciej Żenczykowski <maze@xxxxxxxxxx>

This fixes compiler warnings:

iptables/xshared.h:176:50: error: declaration of 'struct timeval' will not be visible outside of this function [-Werror,-Wvisibility]
extern int xtables_lock_or_exit(int wait, struct timeval *tv);
                                                 ^
iptables/xshared.h:179:57: error: declaration of 'struct timeval' will not be visible outside of this function [-Werror,-Wvisibility]
void parse_wait_interval(int argc, char *argv[], struct timeval *wait_interval);
                                                        ^

Test: builds with less warnings
