Speed up FirewallController startup.
FirewallController::createChain runs iptables commands to remove
the newly-created chain from fw_INPUT. This is not necessary,
because createChain is only called from setupIptablesHooks, which
is only called immediately after initIptablesRules, which clears
fw_INPUT. So there is nothing to delete.
Removing these unnecessary commands speeds up netd startup by
~150ms. Before:
