Auto merge of #8780 - ehuss:git2-1.48, r=alexcrichton

[beta] backport libgit2

This is a backport of #8778 to beta. The reason is that #8517 has started showing up again on rust-lang/rust CI, and I think it is important to fix that.

This is risky, because this is a large update with a lot of untested changes. However, I think the risk is worth it to fix #8517.

This also includes #8772 to get Cargo's CI to pass. I think the risk for that is low (the [changes](toml-rs/toml-rs@0.5.6...0.5.7) are small).  However, I'd be fine with just modifying the tests to pass if you want to drop it.
