In the overlay driver, check if metacopy is enabled, and report it along
with other status information.

If in storage.conf I set the mount options to:
mountopt = "nodev,metacopy=on,redirect_dir=on"
This will turn on redirect_dir but the useNaiveDiff does not currently check
this option. This will cause container images on commit to not be saved
correctly.

When use overlay2 as the graphdriver and the kernel enable
`CONFIG_OVERLAY_FS_REDIRECT_DIR=y`, rename a dir in lower layer
will has a xattr to redirct its dir to source dir. This make the
image layer unportable. This patch fallback to use naive diff driver
when kernel enable CONFIG_OVERLAY_FS_REDIRECT_DIR
