    build: stop using INCLUDES, deprecated by automake 1.7
    
    We already depend on automake 1.9, so using the replacement of
    INCLUDES (AM_CPPFLAGS) won't hurt, especially now that it is
    a warning shown by default since automake 1.13, as evidenced by
    this build log of mine:
    
    Makefile.am: installing './INSTALL'
    eel/Makefile.am:5: warning: 'INCLUDES' is the old name for 'AM_CPPFLAGS' (or '*_CPPFLAGS')
    eel/Makefile.am: installing './depcomp'
    parallel-tests: installing './test-driver'
    libnautilus-extension/Makefile.am:7: warning: 'INCLUDES' is the old name for 'AM_CPPFLAGS' (or 
'*_CPPFLAGS')
    libnautilus-private/Makefile.am:5: warning: 'INCLUDES' is the old name for 'AM_CPPFLAGS' (or '*_CPPFLAGS')
    nautilus-sendto-extension/Makefile.am:3: warning: 'INCLUDES' is the old name for 'AM_CPPFLAGS' (or 
'*_CPPFLAGS')
    src/Makefile.am:13: warning: 'INCLUDES' is the old name for 'AM_CPPFLAGS' (or '*_CPPFLAGS')
    test/Makefile.am:3: warning: 'INCLUDES' is the old name for 'AM_CPPFLAGS' (or '*_CPPFLAGS')
