Update aruba dependency (#2609)

* Depend on latest Aruba release
* Aruba has deprecated `in_current_directory` fix that
* Remove remaining use of in_current_dir
* Replace use of clean_current_dir with setup_aruba
* Remove use of deprecated #dirs method
* Replace #remove_file with #remove
* Replace #set_env with #set_environment_variable
* Replace call to #run_simple with #run_command_and_stop
* Remove custom fail-with-output step
* Remove custom pass-with-output step
* DRY up output checks by reintroducing all_output helper
