multiple occurrences of sudo in run-leda.sh

[razr]

Describe the bug
There are multiple occurrences of sudo in run-leda.sh which are undocumented. It is not transparent what this script is doing/could do with the machine after acquiring sudo privileges.

To Reproduce
Steps to reproduce the behaviour:

$ grep sudo ./run-leda.sh
TUNCTL="sudo tunctl"
IFCONFIG="sudo ip"
IPTABLES="sudo iptables"
    sudo bash -c "echo 1 > /proc/sys/net/ipv4/ip_forward"
    sudo bash -c "echo 1 > /proc/sys/net/ipv4/conf/$TAP/proxy_arp"
        echo "Do you wish to install $package using sudo?"
                    sudo apt-get install -y $package;
sudo qemu-system-x86_64 \

Expected behaviour
no sudo commands

We decided to remove all occurrences of sudo in the run-leda script and making it simpler.

If anybody wants to (or needs to) use a different type of network setup, a modification of the script is needed.
