sngltriggertable.c: remove references to EventIDColumn

- I don't know why this was put in, but the SnglBurstTable row type does
  not have an EventIDColumn structure in it, it has a normal long int.
  there is a patch waiting to be merged into lalsuite that removes this
  structure declaration from lalmetaio's header files altogether which will
  break this code.
