kvm-xfstests: unmount /results before shutting down

From: Eric Biggers <[email protected]>

kvm-xfstests shuts down the VM with 'poweroff -f', which with old versions of systemd's 'poweroff' command (including the version included in Debian Jessie) does not call sync(). This could cause data written to the /results filesystem to be lost. Work around this by unmounting /results before shutting down.
