ci: handle sudo in actions-install.sh

We run our tests as root in containers and VMs. Those platforms do not
have sudo when running Debian-based Linux distributions. Use a small
bash function to eliminate the need to install sudo when we are running
as root.

This function just checks for the existence of sudo and uses it when
installed but does nothing when it is not installed. Using this function
eliminates the need to install sudo before we start installing all the
other packages.
