Alexander Larsson 1e90a18a08 Don't rely on mkdir returning EEXISTS (fixing NFS) ...

For NFS mounts if we call mkdir() on a read-only mount (such as when
we've created a read-only bind mount) the kernel will nor return EEXIST
even when the directory exists, instead returning EROFS.

So, we add (and use) an ensure_dir() helper that stats before calling
mkdir.
