History
Jim Meyering 032a549481 id,groups: with no user name, print only real and/or effective IDs, 
... i.e., don't use the getpw* functions.

Before this change, running groups or id with no user name argument
would include a group name or ID from /etc/passwd.  Thus, under unusual
circumstances (default group is changed, but has not taken effect for a
given session), those programs could print a name or ID that is neither
real nor effective.

To demonstrate, run this:

    echo 'for i in 1 2; do id -G; sleep 1.5; done' \
      |su -s /bin/sh ftp - &
    sleep 1; perl -pi -e 's/^(ftp❌\d+):(\d+)/$1:9876/' /etc/passwd

Those id -G commands printed the following:

    50
    50 9876

With this change, they print this:

    50
    50

Similarly, running those programs set-GID could make them
print one ID too many.

* src/group-list.c (print_group_list): When username is NULL, pass
egid, not getpwuid(ruid)->pw_gid), to xgetgroups, per the API
requirements of xgetgroups callee, mgetgroups.
When not using the password database, don't call getpwuid.
* NEWS (Bug fixes): Mention it.
* tests/misc/id-setgid: New file.
* tests/Makefile.am (TESTS): Add it.
(root_tests): It's a root-only test, so add it here, too.
