tests: add get_one_kata_node() to tests_common.sh

Browse Source 
The introduced get_one_kata_node() returns the first node that
has the kata-runtime=true label, i.e., supposedly a node with
kata installed.

This is useful for tests that should run on a determined worker
node on a multi-nodes cluster.

Fixes #7619
