t/t2000-wreck-env.t: add tests for wreck global environment

Add tests for wreck global environment lwj.environ, and corresponding
commands to manipulate and use that environemnt.

Note: the test is split from t2000-wreck.t but still prefixed with
t2000 for easier test devlepment, parallel tests, etc. Since this is
short-lived code, it is probably ok for now.
