Enable TCmalloc for all throughput jobs
TCmalloc is now also beneficial for HLT1 throughput tests. The main reason is, since the hierarchical SOACollection MR (lhcb/LHCb!3353 (merged)), one allocation is done per field. This was supposed to be mitigated by using the event local allocator, but this solution is not scalable nor better than using TCmalloc.
