linux-user: add ioctl(SIOCGIWNAME, ...) support.

Allow to run properly following program from linux-user:

/* cc -o wifi wifi.c */

#include <stdio.h>
 #include <sys/ioctl.h>
 #include <sys/types.h>
 #include <sys/socket.h>
 #include <linux/wireless.h>
 #include <netinet/in.h>
 #include <arpa/inet.h>
 #include <string.h>

int main(int argc, char **argv) {
int ret;
struct ifreq req;
struct sockaddr_in *addr;
int s;

if (argc != 2) {
        fprintf(stderr, "Need an interface name (like wlan0)\n");
    return 1;
    }

s = socket( AF_INET, SOCK_DGRAM, 0 );
    if (s < 0) {
        perror("Cannot open socket");
        return 1;
    }
    strncpy(req.ifr_name, argv[1], sizeof(req.ifr_name));
    ret = ioctl( s, SIOCGIWNAME, &req );
    if (ret < 0) {
    fprintf(stderr, "No wireless extension\n");
        return 1;
    }

printf("%s\n", req.ifr_name);
    printf("%s\n", req.ifr_newname);
    return 0;
}

$ ./wifi eth0
No wireless extension

$ ./wifi wlan0
wlan0
