tests: run k8s-file-volume on a given node

Browse Source 
This test can give false-positive on a multi-node cluster. Changed it to
use the new get_one_kata_node() and the modified exec_host() to run the
setup commands on a given node (that has kata installed) and ensure the
test pod is scheduled at that same node.

Fixes #7619
