[libgpiod][PATCH 8/9] bindings: python: tests: migrate the system module to multi-phase init

[Vincent Fazio <vfazio@gmail.com>]

Single-phase initialization has been classified as legacy within CPython
documentation [0] with multi-phase being its successor [1].

As such, switch to the new methodology.
