Use a correct scale factor for Gaia avatar images

BUG=341607
TEST=Make sure that you have the --new-profile-management flag turned on, at least two profiles, and at least one of them signed in. Go to chrome://settings. All the users should display an avatar image in the Users section, including the signed in users, which will have their Gaia photo.
