Add new package to debug multicast setups. This is required to use kselftests script for network testing. net-mtools is used instead of mtools as it does conflicts with another package that is also called mtools. Some additional patch from Vladimir Oltean are added to make the tool works on kernel selftests scripts. Signed-off-by: Christian Marangi <ansuelsmth@gmail.com>
