Add support for FLAG_ACTIVE_LOW in libgpiod

During the port to meson, this parameter needs to be set to avoid a
build error. Instead of defaulting to zero, it makes sense to use
FLAG_ACTIVE_LOW where appropriate.

The benefits are that get_value() returns the asserted status of the
GPIO which simplifies checking for events, and 'gpioinfo' now shows
which GPIO lines are configured as active-low.

Tested:
Confirmed that both active-high and active-low events are detected
correctly.
