pstree: fix prepare_dummy_pstree after rework of PID namespace

Browse source 
Since commit 84eedc49a (pstree: Make lookup_create_pid() able to create
tasks with pid->level > 1) the read_pstree_image function presumes that
namespaces image is already parsed.
This patch ensures that this is the case for prepare_dummy_pstree users.
