[libgpiod][PATCH] bindings: python: tests: skip some reconfigure tests on older kernels

[Vincent Fazio <vfazio@xxxxxxxxx>]

Commit 40db20e added tests to ensure that lines that were either missing
from a reconfigure call or were included but had no LineSettings defined
would _not_ change configuration.

However, this functionality requires the changes from kernel commit
b44039638 to work as expected. This commit exists in the 6.10 kernel and
was backported to 6.9.8 [0].

Now, these tests are skipped if the kernel version is older than 6.9.8.

Fixes: 40db20eec045 ("bindings: python: tests: extend reconfiguration tests")
