thermal-hal: Add support for new thermal HAl v2 binary
Add support for new thermal HAL v2 binary, which can listen to the thermal
framework netlink messages instead of the uevents sent by the userspace
governor. This new binary should be selected only for the kernel version
supporting the new netlink messages in thermal framework.
