Update xtrabackup package name for Ubuntu 20.04

Percona no longer includes the generic package name 'percona-xtrabackup' in their Ubuntu 20.04 focal fossa release of percona-xtrabackup. The package name 'percona-xtrabackup-24' must be used instead. This can be verified in the package names included by percona-release, listed at https://repo.percona.com/apt/dists/focal/main/binary-amd64/Packages
