test: implement low-risk test optimizations

Reviewing the performance of http tests in the smartos
CI runs revealed that a handful of HTTP related tests
are running way longer than they should, with some hitting
upwards of 66 seconds!

- Ten HTTP/HTTPS tests now close connections
  deterministically instead of waiting 66 seconds.
- Two HTTP/2 tests use an explicit 64KiB stream window
  and 3MB payload, while restoring timeout assertions.
- Estimated SmartOS CI saving: about 4.5 minutes at -j4.
