Add an API to do the equivalent of `chmod [-r] MODE PATH` for NTFS filesystems. Files created on a linux ntfs-3g mount can not change permissions directly. New files and directories are created with rough windows equivalent of `chmod 777`. These wide open permissions can generate security warnings on windows after virt-v2v installs bits into `Program Files\Guestfs`. Behind the scenes we use `ntfssecaudit(8)` from `ntfsprogs` which is already part of the appliance. We only expose the chmod-style feature; the rest of `ntfssecaudit` is concerned reporting and managing fine grained windows security info which is way more than we need. Also note, `ntfssecaudit` needs to run on an unmounted partition so using this is more complicated than a traditional `chmod` call.
