Embedded: fix sercomm test
The external sercomm_drv_[un]lock() functions are defined as stubs in
case of non-embedded build only which causes linking issue with
sercomm_test. Let's define the same stubs in sercomm_test
unconditionally - the implementation details of the locking are
irrelevant for the test anyway.
