add chopped IPA ping test to BTS tests

Run the chopped IPA ping test from the IPA_Testing module
as part of the BTS test suite. Contrary to the BSC version
of this test, this test listens for an IPA connection rather
than connecting to an IPA server. Make code in the IPA_Testing
module for accepting connections actually work.
