evas: Give a parent to duplicated event objects

This comes back to an earlier situation where the fake event objects
created by efl_input_dup() had a parent (it should be the evas or maybe
the window). But that led to issues as efl_unref() would print error
messages. Using efl_allow_parent_unref_set() we hide the error message,
because in this situation we want the caller to use efl_unref() and not
efl_del() (eg. think of bindings...).
