[for-next][PATCH 1/2] ktest: Make the signal to terminate the console configurable

From: Satoru Takeuchi <satoru.takeuchi@gmail.com>

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

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.
