[bug#72342] [PATCH] services: syncthing: incorrect guessing of HOME variable

[Sergio Pastor Pérez]

Fixed the issue described here:
https://lists.gnu.org/archive/html/help-guix/2024-01/msg00034.html

Fix `syncthing-shepherd-service` failing to guess the correct `HOME`
environment variable when it's `<syncthing-configuration>` does not have a
value for the `home` or `user` fields.

Hello.

Ludo asked[1] to send a patch to fix `home-syncthing-service-type` not guessing 
the correct value
for the `HOME` environment variable. Since the discussions seems stalled, here 
you
have the patch.

Have a great day!
Sergio.
