e2e_node: port privileged pod tests from test/e2e/priviliged.go
The ported test is functionally the same as the original test.
The main difference between the two tests is that the original test relies on
`kubectl` to exec into the container, while the latter directly uses the REST
client of the apiserver. This avoids the need to copy kubectl to the node under
test.
