copy_process: fix CLONE_PARENT && parent_exec_id interaction
commit 2d5516cbb9daf7d0e342a2e3b0fc6f8c39a81205 upstream.
CLONE_PARENT can fool the ->self_exec_id/parent_exec_id logic. If we
re-use the old parent, we must also re-use ->parent_exec_id to make
sure exit_notify() sees the right ->xxx_exec_id's when the CLONE_PARENT'ed
task exits.
Also, move down the "p->parent_exec_id = p->self_exec_id" thing, to place
two different cases together.
