test2092 verifies that when only NTLM credentials are available and
CURL_DISABLE_NEGOTIATE_NTLM is active, SPNEGO auth is silently skipped
and the request is sent without an Authorization header.
test2093 verifies that Kerberos credentials still succeed when built
with CURL_DISABLE_NEGOTIATE_NTLM.
Both tests require the negotiate-ntlm-disabled feature, which is
reported by curl --version as "SPNEGO-no-NTLM" when the compile-time
option is active.
