Alexander Bokovoy 3e27dc4847 daemons: report status to systemd even when running in foreground

When systemd launches samba services, the configuration we have in
systemd service files expects that the main process (/usr/sbin/*)
would use sd_notify() to report back its status. However, we only use
sd_notify() when running become_daemon().

As a result, samba/smbd/winbindd/nmbd processes never report back its
status and the status updates from other childs (smbd, winbindd, etc)
are not accepted as we now have implied NotifyAccess=main since commit
d1740fb3d5a72cb49e30b330bb0b01e7ef3e09cc

This leads to a timeout and killing samba process by systemd. Situation
is reproducible in Fedora 33, for example.

Make sure that we have required status updates for all daemons in case
we aren't runnning in interactive mode.
