Whitelist Trezor Bridge / Trezor Suite localhost:21325
Trezor Suite (a companion app for Trezor Hardware Wallet - http://suite.trezor.io) is an application that bundles trezord binary to allow communication with the Trezor USB device.
The trezord daemon starts a server on localhost port 21325, but the Suite app cannot connect to it.
This MR adds exception for localhost:21325 into ferm.conf
