Assignment of "introspection" as default PACKAGECONFIG value does not
reflect gobject-introspection being globally enabled or disabled.
As a result, graphene compilation used to fail when g-i was disabled.
Use standard means to enable or disable introspection based on machine
and distro features, as implemented by gobject-introspection class.
