s3:auth: fix create_token_from_sid() to not fail in the winbindd case
Commit 1c3c5e2156d9096f60bd53a96b88c2f1001d898a which factored
the sid-based variant out of create_token_from_username() broke
the case of a user handled by winbindd in that the "found_username"
was set to NULL which caused the function to fail with
NT_STATUS_NO_MEMORY further down.
This patch fixes the function so that the case of found_username == NULL
is cleanly separated from the NO_MEMORY case and the caller can provide
the username in this case, if required.
This fixes bug #9457.
