optional dependency `cpu-features` install error

## Investigation

Even though `cpu-features` is an optional dependency, I'm not sure why it is installed. Doesn't seem to affect anything AFAIK. The error is because `python@2` is no longer included in macOS Monterey 12.3 or greater: https://developer.apple.com/documentation/macos-release-notes/macos-12_3-release-notes#Python

I'm using nodejs-14 with npm@6, so it is not because of the automatic install of optional dependencies of npm@7.

## Workaround

To get rid of this error, users have to either:
1. install python v2 manually: https://www.python.org/downloads/release/python-2713/
2. symlink an existing python@3 (may cause issues): https://dev.to/malwarebo/how-to-set-python3-as-a-default-python-version-on-mac-4jjf
3. Configure their python for node-gyp (after installing python@3): https://github.com/nodejs/node-gyp#configuring-python-dependency

## Fix

Dependency tree:
```
$ npm ls cpu-features
└─┬ @openwhisk/wskdebug@1.4.0
└─┬ dockerode@3.3.1
└─┬ docker-modem@3.0.3
└─┬ ssh2@1.10.0
└── UNMET OPTIONAL DEPENDENCY cpu-features@0.0.4
```

Make sure this optional dependency is not installed, somehow. This will require a fix in the dependencies of wskdebug, not wskdebug itself.

Trace the reported dependency chain from @openwhisk/wskdebug through dockerode, docker-modem, ssh2, and cpu-features; no repository file is named in the issue. Reproduce npm install on macOS Monterey or newer and determine whether the dependency chain can avoid installing cpu-features; done means installation no longer triggers the Python 2/node-gyp error.
