feat: sap_hana_install: Useless error messages if there are unrelated SAR files in the HANA software directory

Feature/Enhancement request

If the role sap_hana_install finds SAR files which are not used during HANA installation (e.g. SAPEXEDB_300-70007806.SAR, the error message of task SAP HANA hdblcm prepare - Move files into the correct place, default is not really helpful.
Example:

    stderr: |-
        ls: cannot access '*/': No such file or directory
        mv: missing destination file operand after 'SIGNATURE.SMF'
        Try 'mv --help' for more information.
        mv: missing destination file operand after '..'
        Try 'mv --help' for more information.

The root cause for this behavior is that the non-HANA related SAR files (typically?) do not have a subdirectory but expand directly in the current directory, which is sap_hana_install_software_extract_directory }}/tmp for HANA SAR files. So in case of non-HANA SAR files, the result of the ls command in this sequence is not what it needs to be.
