(dali_env) Fix setenv output
(dali_env) Fix setenv output

Problem:  Running "dali_env -s" does not output the correct setenv information.
Solution: This happened because we were doing a string inequality check using "!=".
          We should use "ne" instead.
          Additionally, ensure we only look for "dali-env" as our root dir explicitly, i.e.
          it should not be dali-env-blah. In that case, a dali-env subdirectory should be used
          as the root.
          Also ensuring that we do not create a new dali-env folder if it already exist in the
          current working directory root path.
