rx for datadir

In xtrabackup documentation it is mentioned that non root OS user required rwx permission on the data directory for taking a backup:
https://www.percona.com/doc/percona-xtrabackup/LATEST/innobackupex/privileges.html#permissions-and-privileges-needed
In tests, it can be seen that the backup works even without write permissions.
