When QEMU is used without any graphical window,
QEMU execution is terminated with the signal (e.g., Ctrl-C).
Signal processing in QEMU does not include
qemu_system_shutdown_request call. That is why shutdown
event is not recorded by record/replay in this case.
This patch adds shutdown event to the end of the record log.
Now every replay will shutdown the machine at the end.

Hi,

This series failed the docker-quick@centos7 build test. Please find the testing commands and
their output below. If you have Docker installed, you can probably reproduce it
