[beta] Fix TcpListener::accept() on x86 Android on beta by disabling the use of accept4.

This is the same as rust-lang#82475, but for beta.

In a nutshell: `TcpListener::accept` is broken on Android x86 on stable and beta because it performs a raw `accept4` syscall, which doesn't exist on that platform. This was originally reported in rust-lang#82400, so you can find more details there.
