```
std.net.listen: fix Windows API use

In a previous commit I removed a load-bearing use of `@hasDecl` to
detect whether the SO.REUSEPORT option should be set. `@hasDecl` should
not be used for OS feature detection because it can hide bugs.

The new logic checks for the operating system specifically and then does
the thing that is supposed to be done on that operating system directly.

```
