Re-enable cgroup v1 support for Noble 6.14+. Starting in 6.12, cgroup v1
support was placed behind CONFIG_CPUSETS_V1 and CONFIG_MEMCG_V1 which
defaults to n.
There is still plently of workloads that require v1 support. The 6.8
kernel still supports v1. Re-enable v1 support on linux-nvidia-6.14 too.
Set CONFIG_CPUSETS_V1 and CONFIG_MEMCG_V1 to y.
