[mutter] Use standard introspection configure/Makefile bits

[Dan Winship <danw src gnome org>]

commit a66ae4ad551b6b9778d790dd66842a186cae129a
Author: Dan Winship <danw gnome org>
Date:   Sat Mar 5 15:01:33 2011 -0500

    Use standard introspection configure/Makefile bits
    
    This changes the introspection configure flag from
    --with/--without-introspection to --enable/--disable-introspection,
    and changes it so that trying to enable introspection when g-i is not
    installed results in an error, rather than being silently ignored.
