Subject: [PATCH] Fix faasd CE install script for RHEL-based systems

This change removes the check-update command. This command is not
required and caused the script to exit early if packages are not up to
date.

In addition DNF is now used to install packages. DNF is the successor of
YUM on the latest RHEL-based system.
