[PATCH 4/4] kernel-shark: Do not use sudo in install_gui.sh + update README

[Michal Sojka <michal.sojka@cvut.cz>]

Using `make install` to install kernelshark can lead to errors
described in the previous commit. Therefore, we instruct users to use
the provided script install_gui.sh. We update the script not to use
sudo, because it's preferable if users give root privileges explicitly
via command line.
