correct doc about list handler (ltluatex)

The documentation states that of all the functions
in the callback returns true then the callback returns
true as well, but the following example (and the code)
shows that the return value in this case is the head
passed to the callback.

\directlua{
luatexbase.create_callback('foo', 'list', false)
luatexbase.add_to_callback('foo', function(head) print('bar') return true end, 'baz')
print(luatexbase.call_callback('foo', token.scan_list()))
}\hbox{foo}
