app/eventdev: fix terminal colour after control-c exit

Before this commit, a Control^C exit of the test-eventdev application
would print the worker packet percentages, and leave the terminal with
a green colour despite the colour reset being issued after the newline.
By moving the colour reset command before the \n the issue is fixed.
