The version of lsblk on centos8 is missing parameters which this script relies on. This change switches some lsblk calls to blkid equivalent to improve support on hosts older than centos9. There is a similar change proposed to diskimage-builder[1]. This change addresses a specific failure on a wallaby cs8 job failure[2], so this change will be backported.
