erts: Optimize tracer reload test
Without off_heap message queue the GC of the tracer could take
very long and thus delay the code:purge which would in turn allow
the trace generator to generate a lot of more messages which would
make the tracer GC for even longer etc etc. The time taken for the
testcase could go up to as large as 10 seconds and use lots of memory.
