Subject: Add fallback to hostname determination

Use hostname in case if hostnamectl is not available/not functional.
fallback to uname in case if both hostname and hostnamectl are
missed (in containers)

Reference:https://pagure.io/setup/c/ddd74b5d971a734c7e88cda3764f7e059f163b51
Conflict:Adjusting the command execution sequence and add a prompt.
