bindings: cxx: tests: set direction when reconfiguring lines

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 C++ test
case which doesn't do it and now fails due to the rest of the settings
being ignored.
