services: gdm: Properly handle empty extensions lists.
Fixes a bug whereby not extending GDM would lead us to do:
(first '())
in the 'compose' method.
Regression introduced in 305a732a0a19c5810aab401aa7d70eba02ac386b.
* gnu/services/xorg.scm (gdm-service-type)[compose]: Handle the case
where EXTENSIONS is empty.
[extend]: Handle the case where XORG-CONFIGURATION is #f.
