### What does this PR try to resolve? This is a follow-up of <#15935>. Before this Cargo invokes syscalls and check whether it gets ENOTSUP to determine flock is unsupported. However, now the "unsupported platforms" are pre-defined by libstd. Cargo should perhaps return unsupported if a platform is marked unsupported by libstd. Without this, some people on Termux may be affected I guess? See https://github.com/rust-lang/rust/blob/e9b6085088fd671ecfbe4cbebe1d26796d8bfa30/library/std/src/sys/fs/unix.rs#L1395-L1410
