[libgpiod][PATCH v2 retry] core: fix deselection of output direction when edge detection is selected

["J.A. Bezemer" <j.a.bezemer@xxxxxxxxxxxxxxxxxxxxx>]

Fix deselection of output direction when edge detection is selected in
make_kernel_flags(). Use correct flag to perform deselection rather than
a library enum.

For correct usage, there are no visible side-effects. The wrongly reset
kernel flags are always zero already.

For incorrect usage of edge detection combined with output direction,
both output and input directions would have been requested from the
kernel, causing a confusing error. Such usage will now be sanitized, as
intended, into a working configuration with only input direction.
