clutter/keyval: Fix keyval_name() transfer annotation

Browse Source 
clutter_keyval_name() returns a pointer to a static array, not
newly allocated memory. Add a transfer annotation to indicate
that callers must not free the returned memory.

While add it, make the return value const to stress further that
callers shouldn't touch the returned memory.
