Update blazesym snapshot

Update the blazesym snapshot we use. This version includes a new API for
caching process VMA metadata (libbpf/blazesym#991),
which we will require for user space address symbolization. With this
version we also include the Cargo.lock, which is required for the
ongoing nixification work (bpftrace#3787).
