Geo: Fix syncing direct download remote stored Blobs

What does this MR do?

When:

• The primary is configured to store Package Files in object storage
• The primary is configured to serve Package Files with direct download (redirect to presigned remote store URL)
• The remote store rejects requests when they contain unexpected headers

Then currently: Geo secondaries will fail to sync Package Files.

This MR fixes this bug.

The root cause is that HTTP.rb's follow method forwards headers from the original request to the redirected location (in this case Authorization: Gl-Geo ...).

Fixes #323495 (closed)
