"Hide" /Android/data|obb|sanbox/ on shared storage

Implement shouldHideDocument() in the ExternalStorageProvider so that it
resitcts access to 'Android/data/', 'Android/obb/' and 'Android/sandbox'
on the integrated shared storage along with all their content and
subdirectories.

Clean up the abstract FileSystemProvider, specifically all variants of
queryChildDocuments().
