Kernel: T5626: only select required Kernel CGROUP controllers
TL;DR: systemd does not require the performance-sensitive bits of Linux control
groups enabled in the kernel. However, it does require some
non-performance-sensitive bits of the control group logic.

The only controllers required for VyOS to function are the memory and PID
controller required by the container feature. All other controlles can be
disabled.
(cherry picked from commit 86f80f99c57240bda43b99d110de736aef4dea76)
