Improved error message when installing thin-edge.io on unsupported operating systems

[reubenmiller]

Is your feature improvement request related to a problem? Please describe.

If a user tries to install thin-edge.io via the thin-edge.io/install.sh script on a MacOS (which is officially unsupported), then the error reason is very clear that it isn't supported.

Below shows an example of the output

wget -O - thin-edge.io/install.sh | sh -s

Detected package manager: tarball
Detected init system:     
Unsupported argument init system.

Describe the solution you'd like

Some pre-checks would be useful to:

• check if the user is able to use sudo
• check if the os family is supported. e.g. fail on Windows or macOS
