lttng-modules: fix compliation error with 3.2.x -stable kernels

recent -stable kernels have their own fallback definition of is_compat_task

   #define is_compat_task() (0)

To protect against this double definition of is_compat_task we can check
to see if it is already defined, and skip the lttng variant.
