Prevent exfiltration of system files via avatar picker.
This adds mitigations to prevent system files being exfiltrated
via the settings content provider when a content URI is provided
as a chosen user image.
The mitigations are:
1) Copy the image to a new URI rather than the existing takePictureUri
prior to cropping.
2) Only allow a system handler to respond to the CROP intent.
This is a fixed version of ag/17071224, to address b/239513606.
