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

[Bartosz Golaszewski]

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")

Please use BPN in:
FILESEXTRAPATHS:prepend := "${THISDIR}/${PN}-2.x:"

I could send another separate fix, but then it would conflict with
this one, so probably better if you send v2 with it.

This patch is already in master-next so just go ahead and add your
change on top.
