[PATCH 1/4] Revert "qemu: allow passt to self-daemonize"

[Michal Privoznik <mprivozn@redhat.com>]

This reverts commit 0c4e716835eaf2a575bd063fde074c0fc7c4e4d4.

This patch was pushed by my mistake. Even though it got ACKed on
the list, I've raised couple of issues with it. They will be
fixed in next commits.
