proc: Fix swap handling for cgroups v2 (can_use_swap)
On cgroups v2, there are no swap current/max files at the cgroup root, so
can_use_swap must look lower in the hierarchy to determine if swap accounting
is enabled. To also account for memory accounting being turned off at some
level, walk the hierarchy upwards from lxcfs' own cgroup.
