[libgpiod][PATCH] bindings: rust: tests: set direction when reconfiguring lines

[Bartosz Golaszewski <brgl@bgdev.pl>]

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

Linux kernel commit b44039638741 ("gpiolib: cdev: Ignore reconfiguration
without direction") made the direction setting mandatory for line config
passed to the kernel when reconfiguring requested lines. Fix the Rust
test cases which don't do it and now fail due to the rest of the
settings being ignored.
