[libgpiod][PATCH 2/2] bindings: python: support casting line.Value to bool

[Kent Gibson <warthog618@gmail.com>]

Python types default to being truthy when cast to bool, so casting
line.Value to bool always returns True.

Add a line.Value.__bool__() operator to map the line value to bool as
one would intuitively expect, so ACTIVE is True and INACTIVE is False.
