nixos/gnome-settings-daemon: pick up correct .wants directories

In https://gitlab.gnome.org/GNOME/gnome-settings-daemon/-/merge_requests/153
the user target names for GSD components has been renamed for example
from `gsd-a11y-settings.target` to `org.gnome.SettingsDaemon.A11ySettings.target`,
and nowadays `gsd-*.target` are just symbolic links of `/dev/null` and will be
removed in the future.

At the same time, as mentioned in d27212d466d0e79c3d9781b60aa3374d234370c0,
we are adding `systemd.user.targets.<name>.wants` stuff here only because
systemd.packages doesn't pick the .wants directories. Nowadays those GSD components
are managed in `/etc/systemd/user/gnome-session@gnome.target.d/gnome.session.conf`
so it should be safe to remove them.

In this commit we also try to pick up those new .wants directories, see also
https://gitlab.gnome.org/GNOME/gnome-settings-daemon/-/blob/41.0/plugins/meson.build#L57
