[PATCH olang v1] tests: show test name into test execution output

[Carlos Maniero <carlos@maniero.me>]

The test output was printing a bunch of dots *.* during the test
execution. Now the tests are printing in the following format:

./0002_binary_operator_addition.ol                           [ OK ] [  222ms ]
./0005_binary_operator_reminder.ol                           [ OK ] [  264ms ]
./0004_binary_operator_division.ol                           [ OK ] [  259ms ]
./0003_binary_operator_multiplication.ol                     [ OK ] [  252ms ]
./0006_binary_operator_subtraction.ol                        [ OK ] [  260ms ]
./0008_binary_operator_lt.ol                                 [ OK ] [  231ms ]

The script changed from multiple printf calls into a single call to make
sure the scripts can be executed in parallel without breaking the
output.
