Fix macOS CI: prevent curl from detecting partial OpenSSL

curl 7.75.0's NTLM code fails to compile on newer macOS runners because
configure detects a partial OpenSSL installation (missing des.h). Adding
--without-ssl prevents OpenSSL detection while keeping Secure Transport
via --with-darwinssl. Cache key bumped to force a fresh build.
