Weihang Lo 01edb24d3c feat(std): emulate flock for solaris via fcntl ...

Upstream Solaris flock emulation to libstd from cargo.

This is borrowed from
https://github.com/rust-lang/cargo/blob/3b379fcc541b39321a7758552d37e5e0cc4277b9/src/cargo/util/flock.rs#L502-L536
which was implemented by an Oracle employee.
The code has been in cargo since 2022-12.

Python's `fcntl.flock` emulates like this as well:

We did the same thing in
https://github.com/rust-lang/rust/blob/0d0f4eac8b98133e5da6d3604d86a8f3b5a67844/compiler/rustc_data_structures/src/flock/unix.rs#L13-L39
