Don't return a header name from auth.GetCredentials

Almost every caller is using it only to wrap an error
in exactly the same way, so move that error context into GetCredentials
and simplify the users.

(The one other caller, build, was even wrapping the error incorrectly
talking about query parameters; so let it use the same text as the others.)
