Raito BezariusandTom Hubrecht c493fb668e nix/daemon: consider supplementary groups during authentication
Two things happens here:

- we consider supplementary groups that are known for authentication,
fixes #968.

- we check supplementary groups if they are our build users group and
throw an error if they are (new behavior).

Nonetheless, we did not remove the ability for `matchUser` to recurse
and check for groups that the user may have but the connection might not
have communicated as part of their groups, i.e. if a process reduces its
list of groups via a call to setgroups, it will still be authorized.
This will come in another commit.

The authorization NixOS test has been extended with a store ping test
running in systemd with DynamicUser=true *AND* a supplementary group in
allowed-users.
