Switch the sql used to fetch the os release version

[julesyan]

Changes

Changed the SQL from

SELECT OS_VERSION CONCAT '.' CONCAT OS_RELEASE AS VERSION
FROM sysibmadm.env_sys_info

to the new one

SELECT CAST(SUBSTR(DATA_AREA_VALUE, 2, 1) CONCAT '.' CONCAT SUBSTR(DATA_AREA_VALUE, 4, 1) AS VARCHAR(32)) AS OS_VERSION
FROM TABLE (QSYS2.DATA_AREA_INFO('QSS1MRI', '*LIBL'))

This should improve performance
