Replace the JSON marshal/unmarshal round-trip in Inherit() with
copier.Copy. json.Unmarshal reuses existing slice backing arrays
and does not zero struct fields absent from the JSON (omitempty),
so mount options like "ro" from one mount would leak into another
mount at the same backing-array position.
Fixes the case where running:
podman run --pod mypod \
--mount type=bind,src=/a,target=/mylog \
--mount type=bind,src=/b,target=/mytmp,ro=true \
alpine touch /mylog/a
incorrectly fails with "Read-only file system" because /mylog
inherits "ro" from /mytmp.
