Remove mmap() from l2norm.cpp

We use instead a similarly bad method for dealing with l2norming when
there's already data in the database: malloc() a buffer the size of the
data.  This will likely fail in even more cases than the previous
mmap()-the-buffer strategy.

  if(index == (uint32_t) -1) {
    return 1;
  } else {
    return audiodb_track_id_datum(adb, index, datum);
  }
