    Make sure we return unicode strings for process output

    Process output is supposed to be represented with lines, so we should
    put Python strings in the queue (not bytes). Just in case, we do it only
    for Python 3 environment.

    To fix that, we reuse code from utils.execute() linux/windows
    implementations.

    This fixes the TestAsyncProcess.test_async_process_respawns functional
    test for Python 3 environment.
