test: Kill qemu by pidfile rather than ^C

Browse source 
Currently in at least some of the testcases we kill qemu processes we're
done with by issuing a Control-C to the tmux panel it's running in.  That
makes things harder as we try to move towards allowing "headless" testing
without tmux.

So, instead always use an explicit kill on a pid derived from a pidfile
for killing qemu.  Note that we don't need to remove the pidfiles
afterwards, because qemu does that itself when terminated.
