Summary: check_dhcp network iface name too small (cf. bug #1286235)

Initial Comment:
Network interface name is only of 7 real chars (8 including final \0).
VLAN interfaces need longer names ("eth1.1230" is 10 characters long).

Normal Linux systems allow interface names of up to 16 characters (cf <linux/if.h>, constant IFNAMSIZ). check_dhcp uses this constant IFNAMESIZ a few time.

My patch changes

char network_interface_name[8]="eth0";

into

#if IFNAMSIZ > 8
char network_interface_name[IFNAMSIZ]="eth0";
#else
char network_interface_name[8]="eth0";
#endif

so it keeps compatibility with other systems which do not have IFNAMSIZ >= 8 ...
