Add CONNECTIVITY_USE_RESTRICTED_NETWORKS permission to DownloadProvider

Browse Source 
- DownloadManager will use the requestor app's default network to
open a connection. When the VPN app lists the DownloadProvider as
a disallowed application, this will fail with EPERM.
- This is because in R, the DownloadProvider lost its privileges
due to the removal of the CONNECTIVITY_INTERNAL permission. It's
removed without considering the corner case where the
DownloadProvider is excluded from using the VPN. It's the only
case where this makes a difference.
- Adding CONNECTIVITY_USE_RESTRICTED_NETWORKS will give
DownloadProvider the ability to use the VPN again in this case,
fixing the issue.

Bug: 165774987
Test: Build, flash rom and boot to home. Manully test that
      DownloadProvider can download file via VPN.
