Issue

I can't seem to generate working installers due to test.js failing to detect the architecture of host machine correctly.

What I ran?

~$ node _webi/test.js  [any_package_directory]/

What Failed?

{ errors: [], os: 'linux', vendor: 'unknown', libc: 'gnu' }
dbg: Get Project Installer Type for 'lazygit':
[INFO] getLatestBuilds: lazygit
dbg: proj { type: 'valid', detail: true }
tmplParams {
  pkg: 'lazygit',
  tag: '',
  os: 'linux',
  arch: undefined,
  ......
}

Everytime, it fails to identify architecture and returns 'undefined'.

Troubleshooting

~$ node -e "console.log(require('os').arch())"

~$ x64

I looked up on the parsing flow of os.arch() output in test.js and found it being parsed on host-targets.js inside the _webi/build-classifiers.

And it missed parsing x64 into x86_64, let me add the exact snippet,

// arch
  AMD64: { arch: 'x86_64' },
  amd64: { arch: 'x86_64' },
  x86_64: { arch: 'x86_64' },

Adding x64: {arch: 'x86_64'} solved the issue, and all the installers I tested after that were fetching the right releases.

I think this should be a PR, because this is a missed scenario. #1002 is most likely caused by this scenario.

I ran into this issue earlier, while working on #1036, and wrote a simple workaround, tagging 'amd64' explicitly if os.arch() returned 'x64'.

But this is a more sanitized, more proper approach.

Thoughts?
