Update helm charts to reflect latest map pinning changes

#1251 removed the requirement for map pinning using the bpf filesystem. We need to update our helm charts to reflect that change, in particular, removing the parts that set up the bpf filesystem mounts.

@rafaelroquetto I can take a look at doing this - I assume from /charts/beyla/templates/daemon-set.yaml we can remove the entire init container, the bpffs volume mount/volume and the BEYLA_BPF_FS_PATH / BEYLA_BPF_FS_BASE_DIR environment variables?

That would be awesome @marevers. You are correct, the BPF mount is not needed at all and it was the only reason for the init container.

Thanks. I've linked the PR with the removal.
