Rsync is managed by xinetd and by systemd at the same time

[Andrey Epifanov]

Version:
MOS9x

For some reason rsync is managed by 2 system at the same time:
- xinetd
- systemctl

when xinetd is able to bind 874 port, systemcl service failed to start and because of it fuel update failed.

Steps for reproduce:

1. systemctl stop rsyncd
2. service xinetd restart
3. systemctl start rsyncd
