[libgpiod][PATCH 1/2] bindings: python: examples: fix potential glitch in gpioset.py

[Kent Gibson <warthog618@xxxxxxxxx>]

gpioset.py requests lines without setting their output value, and so
sets them all inactive, and subsequently sets them to their requested
value.  This can result in glitches on lines which were active and
are set active.

As this is example code, it is also important to demonstrate that the
output value can be set by the request itself.

Request the lines with the correct output values set in the request
itself.
