Since WORKSPACE should point at the EDK2 tree, the right place to check its validity is edksetup.sh, not BaseTools/BuildEnv. This patch makes sure that BuildEnv is always invoked with a valid WORKSPACE. This lets us show better error messages, and ensures that we never dirty the user's environment. BuildEnv will maintain backwards-compatibility and, should the variable be missing, it will be able to set a default WORKSPACE. Only the sanity checks will be of lower quality. Note that the error message in SetupEnv will never be shown if SetWorkspace sets WORKSPACE=`pwd`.
