remoteit/tasks/install.yml: Refine PR #3201 using Ansible not bash

[holta]

Bonus: using the Ansible approach also avoids duplicate IIAB_LIKE=Ubuntu lines in /etc/os-release e.g. in the rare case when someone reinstalls https://remote.it

Tested on Linux Mint 20.3 Una.

Building on:

• remoteit role fails on Linux Mint ["Your OS or distribution is not supported by this install script."] #3199
• PR Workaround to induce remote.it install on Linux Mint #3201

tested IIAB 8.0 on Linux Mint 20.3 and Medium Build with all the defaults works fine. See http://sprunge.us/Sfk3EG
