Make tile's set_dataplane API compatibility-only
The set_dataplane() API in <sys/dataplane.h> originally supported the Tilera version of Linux as shipped to our customers. Once we started upstreaming the dataplane support in the kernel, the API changed to use fcntl() as part of the current task-isolation patch series. It doesn't seem like continuing to support the old API is useful for newly-compiled code, and even supporting the old glibc binary API on an upstream kernel that supports the new task isolation mode isn't straightforward, since the semantics have changed in ways that make it hard to map the old semantics precisely to the new ones, so just return ENOSYS.
