Merge #15507: test: Bump timeout on tests that timeout on windows

fa852f0e8d test: Bump timeout on tests that timeout on windows (MarcoFalke)

Pull request description:

  Those tests build a ton of blocks and time out for me on Windows with:

  ```
  test_framework.authproxy.JSONRPCException: 'generatetoaddress' RPC took longer than 60.000000 seconds. Consider using larger timeout for calls that take longer to return. (-344)
