[PATCH RESEND 2/5] qemuProcessStartManagedPRDaemon: Don't pass -f pidfile to the daemon

[Michal Privoznik <mprivozn@xxxxxxxxxx>]

Now, that our virCommandSetPidFile() is more intelligent we don't
need to rely on the daemon to create and lock the pidfile and use
virCommandSetPidFile() at the same time.
