[SRU][N:linux-gke][PATCH v2 1/1] UBUNTU: [Config] gke: Build multi-gen LRU but leave it disabled

BugLink: https://bugs.launchpad.net/bugs/2113905

Multi-gen LRU was previously made unavailable to users due to a bug, but
this prevented users from opting in for their particular workload. This
change makes multi-gen LRU available in the kernel, but disabled by
default, so that users can choose to opt-in without changing default
behavior.
