misc: ntsync: mark driver as "broken" to prevent from building

The ntsync code is only partially enabled in the kernel at this point in
time, creating the device node and that's about it.  Don't confuse
systems that expect to see a working ntsync interface by teasing it with
this basic structure at this point in time, so mark the code as "broken"
so that it is not built and enabled just yet.

Once the rest of the code is accepted, this will be reverted so that the
driver can be correctly built and used, but for now, this is the safest
way forward.
