percona-server, percona-xtrabackup: rework naming

When reworking the percona package naming towards the two release
streams "innovation" and "lts", I did not anticipate the case that two
releases are long-term supported in parallel, and that the latest
Innovation release is end-of-life and replaced by a more recent lts.

Hence, the first-level attribute names now reflect the package
major-minor versions again, augmented by attribute names pointing to
respective lts and innovation releases.
