When running runc tests with temp directory with size 500M copying
busybox without preserving hardlinks causes the folder to inflate to
roughly 330M. Copying busybox twice in certain tests causes the /tmp
directory to overfill. Using `-a` preserves links which busybox uses to
implement its choice of binary to run.

`HookState` struct should follow definition of `State` in runtime-spec:
* modify json name of `version` to `ociVersion`.
* Remove redundant `Rootfs` field as rootfs can be retrived from
`bundlePath/config.json`.

This removes the use of a signal handler and SIGCONT to signal the init
process to exec the users process.

When the copyBusybox() fails, the error message should be
propagated to the caller of newRootfs().
