Remove X2HO eNBmbmsEnables variables

- it is spaghetti code: difficult to understand which code paths are
  taken
- the only effect seems to be in the UE log analysis function: it might
  make the log fail. However, we test that iperf is successful
  (Iperf2_Unidir()), and would detect before the log analysis if MBMS
  traffic does not work
- the rest is only messages that likely nobody reads

The real reason for this change is to reduce the number of class members
in the ran.py class, to simplify the functioning of the eNB analysis
function (no self) to reduce dependencies on the ran.py class.
