I thought cpio was always creating the output directory automatically,
but it was silently failing. It would only extract the next rootfs when
run a subsequent time.

This version writes fewer temporary files and tries cpio multiple times
for concatenated archives again.

On Linux >= 6.10, the first rootfs is an extra ghost rootfs of 336K,
that has a corrupted CPIO.
To overcome this issue, do not fail on `cpio --extract`.
