cray: detect shasta os properly (#17467)
Fixes #17299 Cray Shasta systems appear to use an unmodified Sles or other Linux operating system on the backend (like Cray "Cluster" systems and unlike Cray "XC40" systems that use CNL). This updates the CNL version detection to properly note that this is the underlying OS instead of CNL and delegate to LinuxDistro.
