Broken/weird filenames for tarballs created by eessi_container.sh script

[bedroge]

The tarballs in the job's previous_tmp subdirs are all named -<timestamp>.tgz . It's using ${REPOSITORY} in the filename at https://github.com/EESSI/software-layer/blob/2023.06-software.eessi.io/eessi_container.sh#L851, but that's no longer defined after we merged #618.

Also, the script is using tar cf, i.e. without compression, while the extension tgz is used. We should either add an z option, or use .tar.
