[CI] CLBlast: Fix directory name

[SlyEcho]

A recent issue on the CLBlast repo: #479 has caused a new release archive to be created for the same version which has a different file name structure.

Without fixing this the CI will be broken.

In the future, it would probably be better to compile it from source.

The result is visible here: https://github.com/SlyEcho/llama.cpp/actions/runs/5095482951/jobs/9160456905 where I am also adding server.exe but it would be a separate PR.

I wonder if it would make more sense to just blindly extract the CLBlast release and search for the dll incase they change the name on us again. I came into this issue today preparing a Windows non-AVX2 ClBlast build for a friend.

It's not just the .dll file, there's CMake files and headers and libraries.

With tar.exe I could use --strip-components to discard whatever directory name is in the archive file, but I didn't see anything similar for 7z.exe. I haven't tested whether tar.exe can extract .7z files, and while it can do .zip files, I have a suspicion that it won't do .7z files.
