Fix for 1322658 not ported to 2.3 and 2.4 of Xtrabackup

It seems like the fix for restore using --copy-back for partitioned tables with own tablespace was not ported to v2.3 and v2.4 of Xtrabackup. [https://bugs.launchpad.net/percona-xtrabackup/+bug/1322658]

Both PXB 2.3 and 2.4 manuals state this, so users would assume the feature is also available on the new versions.
innobackupex is the symlink for xtrabackup. innobackupex still supports all features and syntax as 2.2 version did, but is now deprecated and will be removed in next major release.
