[PATCH v4 5/8] qemu_process: Enable SCHED_CORE for QEMU process

For QEMU_SCHED_CORE_EMULATOR or QEMU_SCHED_CORE_FULL the QEMU process (and its vCPU threads) should be placed into its own scheduling group. Since we have the dummy process running for exactly this purpose use its PID as an argument to virCommandSetRunAmong().
