[PATCH] ktest: Make the signal to terminate the console configurable.

[Satoru Takeuchi <satoru.takeuchi@gmail.com>]

 Currently ktest send SIGINT to terminate the console.
 However, there are consoles which doesn't exit by this signal, for example,
 in my case, "virsh console <guest OS>". In such case, ktest is blocked in
 close_console(). It prevents to automate tests.

This patch adds new option CLOSE_CONSOLE_SIGNAL which mean the
signal to terminate the console. Since its default value is "INT",
the original behavior isn't changed.
