[BUG] regression for user.present on handling groups with dupe GIDs

[nicholasmhughes]

Description
There are certain scenarios, such as the SLS shown below, prior to 3006.x (tested 3004.2) where membership in groups which happen to have duplicate GIDs with other group names would result in a "clean" run because membership in one of the duped GIDs was found. This seems to be broken while testing 3006.x in our operational environment.

An SLS file such as this:

susan:
  user.present:
    - name: susan
    - gid: 1000
    - home: /home/susan
    - groups:
      - sooooosan
    - allow_gid_change: true
    - allow_uid_change: false
    - optional_groups: []

in a scenario where duplicate group membership is as follows:

# grep ":1000:" /etc/group
debian:x:1000:
sooooosan:x:1000:susan

now results in an error message in 3006.x due to a change in how duplicate groups are checked. Further checking of duplicate group IDs will be necessary to fix this regression.

[ERROR   ] These values could not be changed: {'groups': ['sooooosan']}
local:
----------
          ID: susan
    Function: user.present
      Result: False

Summary for local
------------
Succeeded: 0
Failed:    1
------------

Expected behavior
Changes shouldn't be reported for duplicate groups in the checks performed, since the effective GID is appropriate for group membership.
