Set the users and groups staticallyfeature_CPDX-3521

Cannot set USERADD_ERROR_DYNAMIC to error as it breaks the build.
We need to be carefull when adding new users/groups, to also add
them to files/{groups,passwd}

+# Various packages dynamically add users and groups to the system at package
+# install time.  For programs that do not care what the uid/gid is of the
+# resulting users/groups, the order of the install will determine the final
+# uid/gid.  This can lead to non-deterministic uid/gid values from one build
+# to another.  Use the following settings to specify that all user/group adds
+# should be created based on a static passwd/group file.
+#
+# Note, if you enable or disable the useradd-staticids in a configured system,
+# the TMPDIR may contain incorrect uid/gid values.  Clearing the TMPDIR
+# will correct this condition.
+#
+# By default the system looks in the BBPATH for files/passwd and files/group
+# the default can be overriden by spefying USERADD_UID/GID_TABLES.
