build(nix-shell): use static libc and static build

The non-buildx Dockerfile copies a binary built outside of the docker build, which may be broken if the dependencies are not met. This happens on nix-shell as the deps exist on /nix/store. Get around this by building static binaries in the nix-shell. Signed-off-by: Tiago Castro <[email protected]>
