[Integration] Test executable does not validate embedded streams

[bkietz]

Describe the bug, including details regarding any error messages, version, and platform.

IPC files should contain a valid IPC stream with EOS. Some arrow producers don't guarantee that the EOS is written. However there might be readers depending on simply reading the embedded IPC stream (and depending on the EOS to avoid reading the Footer as a corrupted message) so we should validate stream reading from IPC files as well as file reading.
