bug#75288: gnu: xfce4-session: xflock4 fails to run.

Hello,

Lock does not work anymore on XFCE 4.20, after moving from 4.18.
When I try to run the command manually via the terminal on XFCE 4.20, this
is what I get:

```console
$ xflock4
/gnu/store/yz669dvm1cm9nqcxkm8hq8zzgf0cy96f-profile/bin/xflock4: line 52:
gdbus: command not found
```
This must be because of the introduction of commit 42db188a
<https://gitlab.xfce.org/xfce/xfce4-session/-/commit/42db188a912413d099150dd9f44f008285c8a493>
somewhere around 4.19, making xflock4 dependent on D-Bus.

Regards,
Ashvith

I am having the same issue.

I tried fixing the issue by installing "glib:bin" manually, the error 
"gdbus" error message now goes away, but the program still shuts down 
quietly and does not lock the screen.

Should be fixed in master now, thank you for the report!

Need do a system reconfigure with xfce-desktop-service-type, which add
'/etc/pam.d/xfce4-screensaver' for 'xfce4-screensaver'.
