    Changing login prompt to show root as user

    Switch to root user, wasn't adding "root@" to the prompt in
    case of "sudo su -", for "sudo su" it uses the configuration
    described in /etc/bash.bashrc, but for "sudo su -" it is
    replaced by the $SP1 described in /etc/profile.d/prompt.sh.
    To fix it was necessary to change the regex inside
    /etc/profile.d/prompt.sh to show the user before @.

    Test Plan:

    PASS: Generate new image and check with the changes were
          applied and working.

    After upgrade subcloud linux prompt is different

    The regex in prompt.sh is incorrectly adding [] to around
    user@hostname. This commit removes those brackets in order
    to have the expected format.

    Test Plan:

    PASS: Enter "sudo su -" and verify if the prompt shows
                "root@controller-0:~$".
    PASS: Generate a new .iso with the changes and verify
          if when entering sudo with "sudo su -" it is showing
          "root@controller-0:~$".
    PASS: Install system and verify if prompt show
          "sysadmin@controller-0:~$ "
