tests: More portable installation of SIGINT handler

Browse source 
Our tests install SIGINT handlers using sigaction(), but that isn't
available on Windows / mingw, blocking use of the tests there.  Use the
more portable signal() instead - it's good enough for our needs.  Avoid
strsignal() for the same reason.
