fix vcd

several problems were present:
- there was no comma after "ue0_trx_write_ns_missing" in the array
  eurecomVariablesNames;
  comma was put, and also commas for the last element in the array,
  which doesn't hurt and will prevent future problems
- bad order of values in eurecomVariablesNames, which
  was different from the enum vcd_signal_dump_variables;
  order was checked and fixed
- strange/wrong use of VCD_SIGNAL_DUMPER_MODULE_END/LAST;
  the whole logic was removed/simplified
