[libgpiod][PATCH] README: add --enable-bindings-glib as required argument to build D-Bus

[Bartosz Golaszewski <brgl@xxxxxxxx>]

From: Bartosz Golaszewski <bartosz.golaszewski@xxxxxxxxxx>

GLib bindings to libgpiod are required to build D-Bus and both
--enable-dbus and --enable-bindings-glib options must be passed to
configure so make it clear in the README.
