+Script to regenerate L2 test bundles for cgroupv2 compatibility.

+1. Extracts each .tar.gz bundle

+
+Changes made for cgroupv2 compatibility:
+- Removes 'swappiness' from memory resources (not supported in cgroupv2)
+- Sets realtimeRuntime and realtimePeriod to valid values or removes them
+- Updates rootfsPropagation to 'slave' for better compatibility
