ping: Add ATF-Python tests
ping(8) is an old utility, which has received many changes and updates through the years. Some of these changes may have introduced small bugs, in part due to the lack of tests. Attempt to remedy the current situation by introducing a way to easily add tests. Differential Revision: https://reviews.freebsd.org/D38053
