Path error when deploying a go runtime from Windows

[lauw70]

This is a Bug Report

Description

When determining which files should have an 'executable' flag during the packaging process, paths are not normalized before matching. The pull request that introduced this issue is #5813.
The following paths are not matched:

• dist/server
• dist\server

There is a simple fix: normalize both paths before matching.
Change

serverless/lib/plugins/package/lib/packageService.js

Line 116 in 82cb449

.map(f => f.handler);

To
.map(f => path.normalize(f.handler));

Similar or dependent issues:

• Still cannot deploy Golang code to AWS Lambda via Serverless Framework (On Windows).. #5614 (the aforementioned pull request (Support deploying GoLang to AWS from Windows! #5813) was a fix for this issue)
• Windows: Uploaded binaries cannot be executed #3557

Additional Data

• Operating System: Windows

@pmuens The fix I wrote didn't do the job. Another line must be change:

serverless/lib/plugins/package/lib/zipService.js

Line 95 in a8f5739

const name = file.filePath.slice(prefix ? `${prefix}${path.sep}`.length : 0);

must be changed to:
const name = file.filePath.slice(prefix ? `{prefix}${path.sep}`.length : 0).replace(/\\/g,"/");

path.normalize does not a good job so a regex fix is required.
