Subject: [PATCH] build: fix builds that disable protocols but not digest auth

- Build base64 functions if digest auth is not disabled.

Prior to this change if some protocols were disabled but not digest auth
then a build error would occur due to missing base64 functions.

Fixes https://github.com/curl/curl/issues/12440
Closes https://github.com/curl/curl/pull/12442
