changes:
- ue mcc/mnc 208.93
- use correct key/opc for user
- change addresses in conf file for them to be easier to understand
  (maybe)

With those changes, running:
   sudo ./run_enb_ue_virt_s1
in cmake_targets/tools should work out of the box

The user still has to configure correct IP addresses in
targets/PROJECTS/GENERIC-LTE-EPC/CONF/enb.band7.generic.oaisim.local_mme.conf

We supposed oaisim (enb+ue) machine to be on IP address 10.0.1.1
and EPC (hss, mme, spgw) machine to be on IP address 10.0.1.2.

- rename UE_NO_LOG to DISABLE_LOG_X
  because the name is misleading. The full software
  is impacted, not only the UE part
- same for compilation option ---ue-no-log
  that becomes --disable-log
- keep LOG_X for the standard case, that is the
  case without DISABLE_LOG_X where printf has been
  put. Two reasons:
  * printf is not realtime friendly
  * keep behavior similar for other users who may
    be troubled by different logs that don't add
    any benefit to previous logs
