  1. refactor(cpio): Import 'cavaliergopher/cpio' and expose fields 

    Importing is done to ensure further support is easy to do, as the
library has been left mostly abandoned.

The most important exposal is the raw CPIO header, needed for external
processing.

Although unused, it also exposes the name and entry padding for
entries.

  2. feat(cloud): Introduce partial checks for volume importing 

    The following steps sum up what the new algorithm does:
1.  Send the raw CPIO header -- wait for OK
2.  Send the name of the file (NUL terminated) -- wait for OK
2'. Stop if last entry detected
3.  Send the file content | Link destination -- wait for OK

At any time the volume-import unikernel can error out and report back
the error to kraftkit to forward to the user.
