Compare the HTTP host with drogon and by CPU time

A drogon 1.9 service with the axum baseline's contract joins the benchmark
(memory, fdatasync and crash-safe modes, three IO threads), built from
Debian's packages unpacked under .deps without installing them. drogon
listens once per event loop, so the service picks a free port itself:
with port 0 every loop got a port of its own and the load reached one.

The load generator has one core and saturates near 150k answers a second,
so the harness now also reports answers per second of server CPU time
(all threads). Over three rotated rounds: small GETs 151.6k/s on three
shards (drogon 145.3k, axum 120.9k) and 128k per CPU-second on one thread
(drogon 65k, axum 62k); 1 MiB GETs 2,794/s (axum 1,372, drogon 708);
crash-safe PUTs 5.1-5.8 times axum and 13-30 times drogon; peak RSS
5.0 MiB against 14.4 and 76.5 MiB. --workloads is now a regular expression.
