8253727: [cgroups v2] Memory and swap limits reported incorrectly

Account for interface files for swap and memory being reported independently.
The cgroup v1-like value is now reported by adding the memory.max value to
the memory.swap.max value, and memory.current and memory.swap.current
respectively.
