Remove the netgo tag for Windows build (#22467)

Fix #22370 and more.

Before Go 1.19, the `netgo` tag for Windows does nothing.

But Go 1.19 rewrite the net package code for Windows DNS, and there is a
bug:

* https://github.com/golang/go/issues/57757

This PR just removes the `netgo` tag for Windows build, then the Gitea
for Windows can have the old DNS behavior.
