[PATCH] tests: Skip container tests if namespaces are not available.

[David Thompson]

Repairing the damage I've done to the test suite.  I don't have a
GNU/Linux machine with an old enough kernel to check that the tests are
indeed skipped, but I did verify that the tests still run when user
namespaces are available.

Ludovic, this is exactly the code you suggested on IRC.  Does it still
look OK? :)
