When a command is passed into sandbox using the '-c' argument the command is run directly. This is most helpful when running tests (such as test-dm.sh). Previously the exit code was an unused enum. Change it to be the actual return code from the command so that the script calling sandbox can know if the command succeeded (tests passed). Also remove the now completely unused "exit_state" in sandbox. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Acked-by: Simon Glass <sjg@chromium.org>
