cs_user: Use the scaled face image when choosing a picture from file

Choosing a picture with "Browse for more pictures" passed the original
file to AccountsService instead of the scaled ~/.face copy. AccountsService
rejects icon files larger than 1MB, so large images never updated the
user icon and the menu kept showing the old picture.

Fixes #13489
