fix(community_classifieds): admin gets moderator access automatically

group_classifieds_moderator wasn't implied by anything an Administrator
already has, so a standalone install of just this module (no deployment
layer to seed role groups - the exact scenario this module's soft
membership-detection is designed for) left the installing admin unable
to see the Classifieds app or Moderation queue at all until someone
manually granted the group.

Make base.group_system imply group_classifieds_moderator instead, so
every Odoo Administrator gets it automatically with zero extra wiring.
Verified on a from-scratch database with only community_classifieds
installed (community_membership and tncsc_deployment both uninstalled):
admin's has_group() returns True and "Classifieds" appears in their app
switcher immediately after install.
