Subject: [PATCH 1/2] ktest: add 2nd parameter of run_command() to set the redirect target file

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

If we'd like to set the redirect target file of run_command(),
we should define $redirect before calling this function and should undef it
after calling this function. Since it's user-unfriendly, add 2nd parameter of
run_command() for this purpose.
