Subject: [PATCH] Fix up cgroup2fs in Interop.MountPoints.FormatInfo

`stat -fc %T /sys/fs/cgroup` calls this file system `cgroup2fs`

Add the cgroup2fs file system magic number. Available from:

  - https://www.kernel.org/doc/Documentation/cgroup-v2.txt
  - man 2 statfs

Move cgroup2fs next to cgroupfs in the drive type list, since it is also
DriveType.Ram.
