Don't dry-run package libbpf-cargo as part of publish workflow

We can't really verify the libbpf-cargo package because it
unconditionally attempts to pull libbpf-rs from crates.io, where it
can't find the specified version because it has not yet been published.
For the time being, make do without checking libbpf-cargo.
