lib: wait for fw loaded before starting any test

This is going to check whether the sof-test can be started
after boot/reboot.

If FW LOADING is not a prerequisite for the test, this can be skipped,
by defining NO_POLL_FW_LOADING=true

Another benefit with this change, if FW is not loaded it will be failed
instead of TIMEOUT.
