Switch to using LibCURL_jll / MozillaCACerts_jll

[omus]

I used FTPClient.jl with these changes and the tests there did pass

[omus]

CI failure on Linux is returning CURLE_SSL_CACERT. This failure was previously expected on FreeBSD, macOS, and Windows but it is now also happening on Linux.

Can you re-run CI and see if it fails with the latest LibCURL jll?

[ViralBShah]

Does the Julia build pull libcurl from this jll? Just like openblas_jll, can we have packages that need libcurl_jll to simply use the one that ships with Julia itself?

[staticfloat]

That's part of what JuliaLang/julia#35193 will provide

I submitted a change to LibCURL_jll to store the mozilla ca bundle. It'll require some change here which I'll do once the jll update is pushed and registered, but hopefully that'll solve the cert issues here (and at many other places)

I've pulled in the commits from #78 to get this PR to pass (I don't have access to update the branch for #78)

Everything looks good now. I want to validate these changes with FTPClient.jl but I'll need to do that tomorrow.

Yeah, it's worth checking that the jll binary does ftp correctly. (BTW, it should also do http2 now)

I tested these changes with SMTPClient.jl (which also had numerous reports of certificate problems), and they are all fixed with this change, waiting for a tag here.

Changes work fine with FTPClient.jl. I did notice a failure but I can reproduce the failure without this PR.
