    configure: Adds xkb-utils automake conditional
    
    This adds a NEEDS_XKB_UTILS automake conditional that's set to true if
    either the wayland backend is enabled or the evdev input backend is
    enabled since they both depend on clutter-xkb-utils.c and we need
    to avoid listing the file twice since that leads to duplicate symbols
    and the build fails.

 dnl Instead of using AM_CFLAGS to ensure
 dnl COGL_ENABLE_EXPERIMENTAL_2_0_API is defined while compiling clutter
 dnl and cogl code we use a define in config.h instead. This helps ensure
