Tests don't need to specify $OVERLAY_MOUNT_OPTIONS for overlay mount
helpers. These options have already been assigned to MOUNT_OPTIONS
by _overlay_config_override or by _mount_opts and will be added to
mount command by _common_dev_mount_options in _overlay_mount_dirs.

This commit adds a test to check hardlink breakage when the
overlayfs instance is composed of two different underlying
filesystem instances.
For example,
$ mount -t xfs /dev/loop0 /mnt/test
$ mount -t xfs /dev/loop1 /mnt/scratch
$ mkdir /mnt/scratch/upper
$ mkdir /mnt/scratch/work
$ mount -t overlay overlay -o lowerdir=/mnt/test \
-o upperdir=/mnt/scratch/upper \
-o workdir=/mnt/scratch/work /mnt/merge
