Don't exit 0 if killing epmd is impossible because there's living nodes
Don't exit 0 if killing epmd is impossible because there's living nodes

Living nodes will make `epmd -kill` fail, but there's no way to tell
except by looking at the commands output. With this change, the exit
code will be 1 to indicate failure.
