Merge bitcoin/bitcoin#25426: net: add new method Sock::GetSockName() that wraps getsockname() and use it in GetBindAddress()

Pull request description:
_This is a piece of #21878, chopped off to ease review._
Wrap the syscall `getsockname()` in `Sock::GetSockName()` and change `GetBindAddress()` to take a `Sock` argument so that it can use the wrapper.
This further encapsulates syscalls inside the `Sock` class and makes the callers mockable.
