Revert "archive: Use memfd instead"

* It sucks, seems simplify the conditions, but more syscalls are
  made(read/seek/write), more context switch, futhermore AImageDecoder itself does support
  read raw buffer, and we are not intend to support multi-process decoding

This reverts commit f4826ea727.
