tests: Move HTTP server to (guix tests http).

* tests/lint.scm (%http-server-port, %local-url)
(%http-server-socket, http-write, %http-server-lock)
(%http-server-ready, http-open, stub-http-server)
(call-with-http-server, with-http-server): Move to (guix tests http).
Adjust tests for %HTTP-SERVER-SOCKET as a promise and %LOCAL-URL as a
parameter.
* guix/tests/http.scm: New file.
* Makefile.am (dist_noinst_DATA): Add it.
(GOBJECTS): Add .go files for all of $(dist_noinst_DATA).
(make-go): Depend on $(dist_noinst_DATA).
