Fix broken Dockerfile due to wrong mv argument

[FrostKiwi]

I was getting the error the following error:

[...]

I fixed it by changing the mv command from /llama.cpp/main /main to /llama.cpp /main.
But then I ran into:

, so I sidestepped this issue by simply using cp instead.

I was wrong regarding the path. The issue lied with the deletion of files by use of mv.
llama.cpp/main /main was correct afterall.
