Env.vars: server won't ignore the client env

Make the --ignore_client_env flag a no-op.
The client will pass --client_env flags to the
server even in --batch mode. This simplifies the
code as well as ensuring that the server always
uses the up-do-date client environment.

We'll gradually get rid of all System.getenv calls
in the server, because the server should always
respect the client env.
