go files names should not end with _windows.go

[baywet]

We've had to patch the beta weekly releases for the longest time example
Now those changes are trickling down to v1.
Both set of manual changes are making our weekly releases costlier than they need to (somebody need to check why the CI failed, cherry-pick the patch etc...)

It turns out that some suffixes are special cased for code variants on the platform and since our build agents are mostly linux, the files ending with _windows.go are being excluded.

We should update the go Path segmenter to escape anything ending with:

• _windows.go
• _test.go
• _unix.go
• _others.go
• _amd64.go

(there may be more, finding some official documentation on the topic would be helpful)

The filename suffixes for operating system-specific files are based on the standard GOOS values. This is the complete list
