Yank all broken pkg-config versions from crates.io

[klausi]

On https://crates.io/crates/pkg-config/versions everything below v0.3.2 does not compile with recent Rust versions. They should all be yanked so that cargo only installs working minimal versions.

Thanks for the report! I commented over on the Cargo PR though in that I don't think this is quite the right solution, so I'm going to close this.

This is still an ecosystem-wide problem. It's relatively common for crates to specify pkg-config = "0.3", and this breaks min-versions.

Inability to rely on min-versions causes headaches with maintaining MSRV. For example users or zeroize resort to requiring >=1, <1.4 or =1.3. The newly added package.rust manifest property helps alert users about the problem, but util it starts influencing dependency resolution, it won't solve it.
