Update strings to match the final spec: two forgotten files

Update strings to match the final spec: two forgotten files

These two files were omitted from the main change to update strings
(https://codereview.chromium.org/17320005/). As in that change, this
also removes references to "limited users" in the code.

BUG=248859
TEST=manual
