94b39b52 - [NFC][CAS][Unittests] Pass env for MultiProcess tests (#179949)

[NFC][CAS][Unittests] Pass env for MultiProcess tests (#179949) Set up the test similar to ProgramTest to avoid missing necessary env. eg: In our downstream build, the process would rely on a shared libs, the test would fail to find the dependent lib if we don't pass the env down to multiprocess test.
