[meta-oe][PATCH] libgpiod: selectively enable GObject introspection

[Bartosz Golaszewski <brgl@bgdev.pl>]

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

The oe-core bbclass for GObject introspection sets GI_DATA_ENABLED if
the relevant distro feature is enabled. That means that it's up to the
inheriting recipe to disable it if needed.

For libgpiod: we only want to enable it if any of the GLib based
packages is being generated (GLib bindings, D-Bus daemon or ptest).

This also effectively reverts commit 78a332939f8b (libgpiod_2.2: depend
on glib-2.0) which indiscriminately pulls in GLib for all packages
generated by this recipe which feels like shooting a fly with a cannon.

Fixes: 9626e8a2c8f2 ("libgpiod: update to v2.2")
