Clean fix for the chown race condition on new input devices. Drop init's egid to AID_INPUT while creating the device node, so that it is created with the correct gid. This eliminates the possibility of system_server opening the device node before its permissions are set correctly. Using setegid() allows us to swap back to AID_ROOT immediately after mknod().
