ecore fb: Unbreak ecore_evas_fb.

The ecore_evas_fb module uses ecore_fb_ts_* functions which are only available to EFL internals and not for the general API.

 However, EAPI not being defined in ecore_fb_private.h made the symbols not being exported at all, which in return made execution-time linking not finding them and thus failing.
