While we could continue to use FreeRADIUS 2.x that branch is officially EOL.
So instead of investing time and effort in updating/migrating the patches to
FreeRADIUS 3.x (the module changed quite significantly as it relies solely on
the naeap library in that release), for a protocol that is superseded anyway,
we just remove these scenarios and the dependencies. Actually, the
complete rlm_eap_tnc module will be removed with FreeRADIUS 4.0.
