Subject: [PATCH] Fix IMDS token requests for managed identities

This was broken by a035ee5f9416ef9188533de40b4ab1c37fb7c0af, which
accidentally constructed the IMDS URL with a double slash at the start
of the path. This is not properly routed on the server side, leading to
a 404 error with some very misleading XML.
