Restrict getting the restore process start time to CRaC API

[ThanHenderson]

There is a race condition on the existence of the criu restore process and retrieving its start time, when --restore-detached is passed to criu restore. This patch restrict retrieving the process start time to restoring via CRaC which is not affected.

This test has been removed, but I hadn't removed if from the .xml file.

Edit: I've removed it now.

We only need to restart the sanity.functional tests, the others were passing.
