When listening on a UNIX socket path, Deno currently tries to unlink this path prior to actually listening. The implementation of this behaviour is VERY racy, involves 2 additional syscalls, and does not match the behaviour of any other runtime (Node.js, Go, Rust, etc). This commit removes this behaviour. If a user wants to listen on an existing socket, they must now unlink the file themselves prior to listening.

When listening on a UNIX socket path, Deno currently tries to unlink
this path prior to actually listening. The implementation of this
behaviour is VERY racy, involves 2 additional syscalls, and does not
match the behaviour of any other runtime (Node.js, Go, Rust, etc).
This commit removes this behaviour. If a user wants to listen on an
existing socket, they must now unlink the file themselves prior to
listening.
This change in behaviour only impacts --unstable APIs, so it is not
a breaking change.
