Agent does not compile and run on AIX 7.1 TL0 (requires TL1)

Solution for ZBX-11902 added dependency on AIX API perfstat_partition_config(). This function is available starting from AIX 7.1 TL1 (Technical Level 1). So, Zabbix agent does not compile on AIX 7.1 TL0. Also, compiled on AIX 7.1 TL1, the agent does not start on AIX 7.1 TL0.
