test-client: cleanup imports

Sort imports by name. Also avoid "from signal import SIGINT". I find
it ugly to import names in the current namespace. "SIGINT" should be
refered to by its full name, including the package/namespace.

(cherry picked from commit ee17346cee3c116db5ebebd3f4e4fe81a58944b7)
