bitbake: fetch2/wget: add redirectauth parameter
Add a parameter that limits sending Basic authentication in the
Authorization header to only the first host and not any that we're
redirected to. Ignoring potential security concerns, temporary AWS URLs
will reject any request that includes authentication details in both the
query parameters (from the redirect) and in the Authorization header.
Temporary AWS URLs are now being used for release assets from private
Github repositories. According to the previous discussion linked below,
they're also in use by bitbucket.
