Inaky Perez-Gonzalez 9343cc7ca0 qemu: use a pidfile to avoid killing all and thus enabling parallel runs
When killing QEMU, we defaulted to either killall or find the first
qemu process. This intefered with parallel builds, as we might kill
some other build's qemu process.

This makes QEMU write a pidfile in the local outdir directory and kill
only that when done.
