adduser in Ubuntu 26.10 is failing autopkgtests with the following
111s err: The group `s3afixedg01' already exists, but has a different GID.
Exiting.

systemd-sysused auto allocates starting at 999 and going down. In a
Forky/testing container, it enumerates down to 987

the tests in debian/tests/f/firstlastuidgid.t : test group S3A: uid range
requested by config, no command line : hardcodes values
$prefix='s3a';
$firstuid1=260;
$firstgid1=270;
$fuid = 970;
$fgid = 980;
in autopkgtest in Ubuntu, we apparently have users down to 980 causing
failures. This can be addressed in the test by checking for open ids
