[ Upstream commit bff466bac59994cfcceabe4d0be5fdc1c20cd5b8 ]

Commit 3edfb7bd76bd ("gpiolib: Show correct direction from the
beginning") fixed an existing issue but broke libgpiod tests by
changing the default direction of dummy lines to output.

We don't break user-space so make gpio-mockup behave as before.
