connman: fix crash with iptables 1.6

The struct of xtables_globals has been modified in iptables 1.6.
If connman runs with iptables 1.6, it can crash.

Program received signal SIGSEGV, Segmentation fault.
0x00000000 in ?? ()
0xb7dea89c in xtables_find_target () from /usr/lib/libxtables.so.11
0xb7deac1c in ?? () from /usr/lib/libxtables.so.11
0xb7dea793 in xtables_find_target () from /usr/lib/libxtables.so.11

The the missing function item of xtables is added to xtables_globals.
It can fix the above issue.
