ecore_evas_extn: Fix socket & plug windows
Socket & Plug were broken after 38e6780262
.
Multiple problems here:
- The invalid path was used for the lock file.
- The invalid buffer ID was used for unlock in render_post. That's
because the buffer was switched during output_flush which happens
before render_post. So the buffer would remain locked forever on the
server side (unless maybe some animation was happening there).
@fix
