elm: efl_ui_flip: add fl_ui_flip_eo.h redirection header lost during rename

When this was renamed from elm_flip to efl_ui_flip the _eo.h header was lost
which is needed as redirection. This broke for me in distcheck when the .eo.h
was going to get generated. It also aligns it with the other headers we have
here.
