Subject: Fix building with use_bluez=false

This is a quick and dirty fix for building chromium with use_bluez=false
It prevents initialization and usage of Bluetooth by the browser
It is not supposed to be applied for use_bluez=true
WebAuthn is prevented from using Bluetooth, but it might still work with USB
