tests: make test-trusted use print_function

There was some confusing output format at some places in
test-trusted.py.out, the new print function ends with a newline by
default whereas the old print statement uses a space generally. So the
output in test-trusted.py.out is changed because of some confusing
output format which was produced by print statement
