cmd/cgo: update outdated docs about cgocheck2

such as "fatal error: cgocheck > 1 mode is no longer supported at runtime.
Use GOEXPERIMENT=cgocheck2 at build time instead."

The default setting is GODEBUG=cgocheck=1, which implements reasonably cheap dynamic checks. These checks may be disabled entirely using GODEBUG=cgocheck=0.

It is possible to defeat this enforcement by using the unsafe package, and of course there is nothing stopping the C code from doing anything |
