[Trivial] Remove the metadata semvar causing a warning.

Hey, I have seen the warning from this, but the crate itself adds this metadata, as we can see in install section https://crates.io/crates/libbpf-sys . I think the second part maps to the libbpf against which this is built.
Would it be a good idea to remove (not that this should change anything compilation-wise, as cargo ignores it anyways)

I filed libbpf/libbpf-sys#58 to clarify with the lib author. If I am understanding correctly, the metadata version is used as a human readable indicator for the version of upstream of libbpf used. So it should be safe to remove from the cargo.toml since as you mentioned cargo ignores it.

@YJDoc2 Confirmed with the libbpf author that the metadata can be ignored safely in the cargo.toml. Reference: libbpf/libbpf-sys#58 (comment)
