Add checksums for LibCURL

[DilumAluthge]

These checksums were deleted in #38963.

However:

1. When I run make locally, these checksums are generated.
2. If you look in the deps/checksums/curl file, these checksums are not located there.

Not for me. Have you cleaned out old deps stuff from your repo?

[DilumAluthge]

Yep, I even tried in a brand-new clone and it still generates the checksums.

This is on macOS.

[DilumAluthge]

I get this with a brand-new clone on both macOS and Linux.

[KristofferC]

Yeah, I managed to get it now as well after a git clean -fdX.

Perhaps these two lines should rather be added back: https://github.com/JuliaLang/julia/pull/39625/files#diff-c5e29ac5eae5352c7cd703597b517a569d2a4fee6684dc03f54e891e6883854eL2

I don't really understand why one of the tarballs in there is not used though?

Or since this is for jll, maybe it is better to have them in a separate file like in this PR (it seems we do for the other stdlibs).

Good question. I don't feel strongly either way. @vtjnash since you did the reorganization of the checksums recently, which one would you prefer?

[vtjnash]

Either is fine
