a704d39b29 os: hide SetFinalizer from users of Root
Currently Root embeds a root and calls SetFinalizer on &r.root. This
sets the finalizer on the outer root, which is visible to users of
os.Root, and thus they can mutate the finalizer attached to it.

This change modifies Root to not embed its inner root, but rather to
refer to it by pointer. This allows us to set the finalizer on this
independent inner object, preventing users of os.Root from changing the
finalizer. This follows the same pattern as os.File's finalizer.

Fixes #71617.

57147256e6 os: recognize EFTYPE, EINVAL as a refusal to open a symlink
NetBSD returns EFTYPE when opening a symlink with O_NOFOLLOW.

Dragonfly seems to return EINVAL. Only check for EINVAL on Dragonfly,
since that seems like a bit of a broad net.
