Show visibility status of email in own profile

I've heard many reports of users getting scared when they see their own
email address for their own profile, as they believe that the email
field is also visible to other users. Currently, using Incognito mode
or going over the Settings is the only "reasonable" way to verify this
from the perspective of the user.

A lock indicator should be enough to indicate otherwise. A globe icon
is used if the email address is public.
