MDEV-28205: SST via mariabackup stops on failure while archiving logs

Currenly SST script for mariabackup stops on any failure while archiving
logs, e.g. when unable to create directory, insufficient permissions, gzip
failure, etc. However, in case of such problems, the script should issue
a warning and continue without archiving, but not exit with a fatal error.

This commit adds this fix to the SST script for mariabackup.
