Explicitly cast time value in cmSystemTools::RandomSeed
Use static_cast to avoid warnings like
conversion to ‘unsigned int’ from ‘__time_t’ may alter its value
conversion to ‘unsigned int’ from ‘__suseconds_t’ may alter its value
We do not care if the value is truncated because we are looking for just
32 bits anyway.
