Add Cache-Control to avatar redirects (#16973)

* Add Cache-Control to avatar redirects

This does seem to do the trick to make the Avatar redirects cachable
in Chrome.

In Firefox, it does not seem to work, thought and I found no way to
suppress the requests to the original URLs, I even tried setting an
Etag to no avail.
