[Optimization] Installer - sudo missing

[radim-ek]

Installer use "sudo" in Linux. But sometimes there is not "sudo" and user is under root. And therefore not created systemd service. And ./start.sh" not worked too.

Do you want to install ArozOS to systemd service? (y/n)y install.sh: line 133: sudo: command not found install.sh: line 134: sudo: command not found install.sh: line 154: sudo: command not found install.sh: line 157: sudo: command not found install.sh: line 158: sudo: command not found install.sh: line 159: sudo: command not found ArozOS installation completed!
