percona-xtrabackup is busted in master

[Steven Dake]

Percona xtrabackup released a new version on 10/16/15 which fails during the backup phase of the HA database operation.

The .32 version (broken) prints out:
xtrabackup: uses posix_fadvise().
xtrabackup: cd to
xtrabackup: open files limit requested 0, set to 1048576
xtrabackup: using the following InnoDB configuration:
xtrabackup: innodb_data_home_dir = ./
xtrabackup: innodb_data_file_path = ibdata1:12M:autoextend
xtrabackup: innodb_log_group_home_dir = ./
xtrabackup: innodb_log_files_in_group = 2
xtrabackup: innodb_log_file_size = 50331648

The .13 version (working) prints out:
xtrabackup: uses posix_fadvise().
xtrabackup: cd to /var/lib/mysql/
xtrabackup: open files limit requested 0, set to 1048576
xtrabackup: using the following InnoDB configuration:
xtrabackup: innodb_data_home_dir = ./
xtrabackup: innodb_data_file_path = ibdata1:12M:autoextend
xtrabackup: innodb_log_group_home_dir = ./
xtrabackup: innodb_log_files_in_group = 2
xtrabackup: innodb_log_file_size = 50331648

It appears we are missing some kind of config option to cd to /var/lib/mysql with xtradb.

Also we are using the el6 repositories when we should be using the el7 repositories.

    Encode datadir for xtrabackup

    Xtrabackup previously used a hardcoded datadir. In the latest
    update to xtrabackup, the my.cnf config option datadir is now
    parsed. This variable was unset, causing galera to implode.

This is not fixed. This broke ubuntu because it was not tested.

    Fix broken galera

    A previous commit [1] broke Galera on Ubuntu while trying to fix
    Centos. This fixes the underlying different between the two distros
    and should help prevent that kind of mistake in the future.
