evas: fix png regression issue

Accidentally commit "382c580 evas: add support for .9.png file to PNG loader."
adding the 9 patch feature with small code refactoring missed a line calling
eina_file_map_all taking EINA_FILE_SEQUENTIAL for data decoding.

You can see the previous change adding the line from the following commit.

   e60baa0 evas: change mapping policy to be less agressive into loading file
           in memory.

This is a response to the request of @cedric on D9580
