test: increase limit for network space overhead test

Ben L. Titzer · targos · commit 499969db9e13 · 2019-07-20T11:10:28.000+02:00
This test imposes a limit on the average bytes of space per chunk for network traffic. However this number depends on VM implementation details, and upcoming changes to V8's array buffer management require a small bump to this limit in this test.
