Previously Talos would not shutdown gracefully if hyper-v issued the 'perform_shutdown' call. Said call would execute '/sbin/poweroff' which did not exist in Talos. We hardlink machined to '/sbin/poweroff' and make it send a shutdown API call to PID 1 machined. Fixes #5641 Signed-off-by: Philipp Sauter <philipp.sauter@siderolabs.com>
