fixes #1084 "if all user turns off all interface management and configuration checkboxes, the check_tools shell function is not added to the script but still called". Shell function "check_tools" verifies that system tools iptables script needs to operate properly are installed on the firewall. These are: ip, modprobe and optionally vconfig, brctl, ifenslave. The bug made compiler for iptables to add the call to the function but function definition was missing if user unchecked all "configure interfaces" checkboxes in the Script tab of firewall object settings dialog.
