c8330d4qa: Use node.datadir instead of tmpdir in test framework (MarcoFalke) Pull request description: Commitc53c9831eeintroduced the utility function `get_datadir_path`, however not all places in the code use this util function. Using the util function everywhere makes it easier to review pull requests related to the datadir. This commit replaces datadir path creation with the `datadir` member of `TestNode`, which itself uses `get_datadir_path`.
