feedback: Update language of no-email option.

To be technically accurate, we should not describe this option as
"anonymous"; it's actually properly described as "de-identified".
However, "de-identified" is a bit technical, so change to a more clear
string.

BUG=chromium:1112012
TEST=Deploy to DUT and verify dialog option is as expected
