SLES 16.0 needs additional deps for test user

cat /root/auditScript/logs/sles_16.0_logs.txt
OCI runtime exec failed: exec failed: unable to start container process: exec: "su": executable file not found in $PATH
Build script execution failed in container: 4f983d2a12b9b0038cc551dc2f8787d1f3db44126425423ae1c627afa7e3dce3

In order to use su - test on SLES 16.0 we need to install two deps - util-linux and sudo, before using the former cmd.
