fix at_nas_ue compilation

Wataru Ishida requested to merge wataru/openairinterface5g:fix_at_nas_ue_compilation into develop

On ubuntu 16.04, nettle's version is 3.2. In this case, we need to define 'NETTLE_VERSION_MAJOR' to properly switch how to call 'nettle_aes128.set_encrypt_key' in openair3/SECU/nas_stream_eea2.c

before this patch:

$ build_oai --oaisim -C

-> this fails

$ less log/at_nas_ue.Rel10.txt
