manager: don't skip sigchld handler for main and control pid for services (#3738)

During stop when service has one "regular" pid one main pid and one
control pid and the sighld for the regular one is processed first the
unit_tidy_watch_pids will skip the main and control pid and does not
remove them from u->pids(). But then we skip the sigchld event because we
already did one in the iteration and there are two pids in u->pids.

v2: Use general unit_main_pid() and unit_control_pid() instead of
reaching directly to service structure.
