    nimble/test: Fix LE SC tests
    
    Some LE SC tests depend on known initial values on crypto side.
    With latest update to TinyCrypt provided prng function is used also
    for initial seeding and thus tests were failing. To keep things simple
    just don't initialize random source function when doign unit tests.
