system tests: socket activation: clean up

Multiarch folks are seeing flakes in this test. I can't reproduce
them, but I did notice that the test isn't doing the best possible
job of reporting failures nor of confirming what it purports to test.

Major fix here is to check the exit status of each curl: if we
see the flake again, that will help us track down the failure.

Other fixes are just refactoring, cleanup, and disambiguation
(using the random service name consistently)
