Subject: [PATCH v2 03/14] selftests/nolibc: print running log to screen

When poweroff fails, qemu-system will hang there without any output.

It is very hard to debug in such case, let's print the running log to
the screen to allow users to learn what is happening at the first
glance, without editing the Makefile manually every time.

To get a clean output, the 'grep status' command can be used.
