[Fix] Spawn processes during tests using execPath so that the tests p…

…ass on windows

In some parts of the code the `bin/tape` script was executed directly. This does not always work on windows, causing those tests to fail. So instead `process.execPath` is executed (which is the path to the node binary), and the script is passed as an argument. In other parts of the code, argv[0] was used. This has been made consistent so that execPath is used everywhere.
