[PATCH v2 7/8] sandbox: Write out bloblist when existing

Sandbox provides a way to write out its emulated memory on exit. This
makes it possible to pass a bloblist from one phase (e.g. SPL) to the
next.

However the bloblist is not closed off, so the checksum is generally
invalid. Fix this by finishing up the bloblist before writing the memory
file.
