bug#74082: [PATCH] home: Use %user-log-dir as the log directory for all services.

[Dariqq <dariqq@posteo.net>]

* gnu/home/services/desktop.scm (home-dbus-shepherd-services): Log to
%user-log-dir.
* gnu/home/services/desktop.scm (home-unclutter-shepherd-services): Same.
* gnu/home/services/pm.scm (home-batsignal-shepherd-services): Same.
* gnu/home/services/shepherd.scm (launch-shepherd-gexp): Don't overwrite
default log-file.

---

This patch fixes the inconsistent use of "LOCAL_STATE_HOME/log/" vs "LOCAL_STATE_HOME/shepherd/" for logfiles by changing the (remaining) shepherd services to the shepherd variable %user-log-dir i.e. LOCAL_STATE_DIR/shepherd.

I also removed the --log-file argument from the autostart shepherd invocation which makes it log to the default location LOCAL_STATE_DIR/shepherd/shepherd.log
and removed creation of the shepherd log dir. (comment says shepherd >= 0.9.2 should handle creation of the directory)
Have only tested it with dbus-service and the autostart shepherd because I dont use the other ones.

There is still another slight inconsistency with other home-services that let-bind the logdir, but this is less of an issue imo.
