Merge #13638: tests: Use MAX_SCRIPT_ELEMENT_SIZE from script.py

b9f4b21 tests: Use MAX_SCRIPT_ELEMENT_SIZE from script.py (Daniel Kraft)

Pull request description:

  `p2p_segwit.py` and `test_framework/script.py` both define a constant for `MAX_SCRIPT_ELEMENT_SIZE` (=520 bytes), which is redundant.  This change uses the constant defined in the `script.py` module for `p2p_segwit.py`.
