Support Android OS

[tccloudz]

Is your feature request related to a problem? Please describe.
I use a terminal emulator app (Termux) on my Android phone. I wanted to use the cli on the phone via the emulator app. I was able to install the CLI using npm, however, whenever I try to run any commands an error is returned stating that the Android is an unsupported OS.

What are you trying to do
Be able to run the tool on my android phone as I perform a lot of tasks on the phone, including light development.

Describe the solution you'd like
I am able to successfully install the CLI tool on the phone via the terminal emulator app, I do not see any reason why I am not able to run any of the commands.

Describe alternatives you've considered
As an alternative I was able to install the Force.com CLI successfully and be able to run the commands via that tool.

I'm guessing that if we unblocked the OS check, there'd be a bunch of OS-related things behind it that cause problems (fs structure and permissions, keychains, commands to open stuff in the browser etc).
