LPS-40663 - In the mobile view, the user icon should be the portrait of the user 

Hey @shinnlok,

Attached is an update for http://issues.liferay.com/browse/LPS-40663.  I am sending you this to review the backend changes for the NavTag.java file.  I think we need to localize the alt tag value, but I was not sure how to do that since in the examples I found in the portal, we pass a locale, but the taglib does not pass in anything.

Please let me know if you have any questions.  Thanks!
