Disable TCP detection system for kernel >= 3.10.x

Since 3.10.0, the proc_dir_entry structure is now an opaque object in
the kernel set in fs/proc/internal.h.

I've not yet investiguate how to do the same job without getters for the
field kjackal needs in that object. So for now, disable the detection.
