launcher: do not re-daemonize when USR2 upgrading

This was accidentally enabled when ready_pipe was developed.
While re-daemonizing appears harmless in most cases this makes
detecting backed-out upgrades from the original master process
impossible.
(cherry picked from commit 3f0f9d6d72cf17b34c130b86eb933bbc513b24b3)
