Max Wipfli e8a317023d Kernel: Allow unveiling subfolders regardless of parent's permissions ...

This fixes a bug where unveiling a subdirectory of an already unveiled
path would sometimes be allowed and sometimes not (depending on what
other unveil calls have been made).

Now, it is always allowed to unveil a subdirectory of an already
unveiled directory, even if it has higher permissions.

This removes the need for the permissions_inherited_from_root flag in
UnveilMetadata, so it has been removed.
