run-tests.py: inherit PYTHONHASHSEED from environment if set

This makes it possible to fix the seed by using for instance
  PYTHONHASHSEED=7 ./run-tests.py ...

This can be very convenient when trying to debug problems that are influenced
by hash values. Try different seed values until you find one that triggers the
bad behaviour and then keep that while debugging.

The value 0 will restore default Python behavior and disable randomization.
