This change turns the OpenHarmony systemd services into dummy services
that doesn't start them. Instead, the preinit script will check for
these services state and start the corresponding services if their
systemd unit are enabled.

These are services using the System Ability framework through the
executable sa_main. These services depend on and are started after the
System Ability Manager service (samgr).

Most of them are noop for now. No process is created after sa_main exits
for all of these services.
