Fix dead code
The check if buffer == NULL is always false, since buffer is an autoamtic variable allocated when entering the function. What we instead want to do is to check if the string is empty after the call to exif_get_info(), since that means we could not read any exif information. When the code once more is enabled, I discovered that we need to copy the information string into info_buf as well as into buffer, since it is the former that is used to print the exif information on top of the picture. Without this change, imlib warns about trying to write NULL strings.
