package/libgpiod: disable examples

This will fix a build failure with libgpiod in version 1.6.2

Even though the examples are not built by default, we explicitly
disable them, to be future-proof in case that default changes in
the future.

+Subject: build: add a configure switch for building examples
+
+Example code for bindings is currently always built if bindings are
+enabled. Make it conditional with a new configure switch.
