Christian Brauner 8423b3bd7d ovl: handle idmappings in layer open helpers ...

In earlier patches we already passed down the relevant upper or lower
path to ovl_open_realfile(). Now let the open helpers actually take the
idmapping of the relevant mount into account when checking permissions.
This is needed to support idmapped base layers with overlay.
