daemon: Use the guest GID in /etc/group.
Partly fixes <https://issues.guix.gnu.org/77862>.
Fixes a bug whereby, when running guix-daemon unprivileged, /etc/group
would contain the wrong GID for the “nixbld” group. This inconsistency
would lead to failures in the Coreutils test suite, for instance.
* nix/libstore/build.cc (DerivationGoal::startBuilder): Use ‘guestGID’
when writing /etc/group.
* tests/store.scm ("/etc/passwd and /etc/group"): New test.
