daemon: "the service is not installed"

Hi Vishesh,

I just installed git-auto-sync on my Ubuntu 22.04.1 LTS as described in the Installation section for Ubuntu/Debian. Installation worked without issue.

I added a couple of respositories I want to sync using git-auto-sync:
```
❯ git-auto-sync daemon add /home/me/src/ppp/repo1
Installing git-auto-sync as a daemon
Starting git-auto-sync-daemon
❯ git-auto-sync daemon add /home/me/src/ppp/repo2
Starting git-auto-sync-daemon
❯ git-auto-sync daemon add /home/me/src/ppp/repo3
Starting git-auto-sync-daemon
❯ git-auto-sync daemon add /home/me/src/ppp/repo4
Starting git-auto-sync-daemon
❯ git-auto-sync daemon ls
/home/me/src/ppp/repo1
/home/me/src/ppp/repo2
/home/me/src/ppp/repo3
/home/me/src/ppp/repo4
❯ git-auto-sync daemon status
2022/08/29 12:02:50 the service is not installed
```

As a result of the daemon not running, the repos are not synchronised.

Is there anything I am doing wrong or is there any prerequisite bevor installing git-auto-sync?

Regards
Peer
