adding verification about curl linking details

[shiftkey]

Before I look to address #109 (by building curl myself? by statically linking?) I'd like to confirm the mismatch between libcurl.so.4 and CURL_OPENSSL_3 that I've painted myself into.

Cool, looks like it's working as intended:

File: ./libexec/git-core/git-remote-http
