docker run --storage-opt=size=<x> fails within sysbox container with XFS /var/lib/docker

On a host with an XFS filesystem mounted at /var/lib/docker, docker run --storage-opt=size=<x> succeeds on containers (runc and sysbox-runc) launched from the host, but fails on containers launched from within a sysbox-runc container with a volume mounted /var/lib/docker, running dockerd.

Steps to reproduce:

1. Mount an XFS filesystem at /var/lib/docker on the host:

# mount -v | grep /var/lib/docker
/dev/sdb on /var/lib/docker type xfs (rw,noatime,attr2,inode64,logbufs=8,logbsize=32k,prjquota)

2. Launch a sysbox container e.g. docker run --runtime=sysbox-runc --mount=type=volume,dst=/var/lib/docker and launchdockerd within the container. Confirm that, within the sysbox container, /var/lib/docker is indeed XFS (as it should be, as it will be located within /var/lib/docker/volumes on the host):

# mount -v | grep docker
/dev/sdb on /var/lib/docker type xfs (rw,noatime,attr2,inode64,logbufs=8,logbsize=32k,prjquota)

3. Now, within the same sysbox container, running docker run --rm -it --storage-opt=size=<x> debian bash will fail:

# docker run --rm -it --storage-opt=size=2G debian bash
docker: Error response from daemon: --storage-opt is supported only for overlay over xfs with 'pquota' mount option.
