If innodb_data_home_dir path specified in the configuration file
then rsync IST/SST will fail because the wsrep_sst_rsync.sh script
does not read this parameter from the configuration file and then
tries to find the data files in the default directory.
To fix this error, we need to add reading of the innodb_data_home_dir
configuration parameter to the rsync-related SST script.
