[23573] Add blackbox tests for original writer info in ddspipe

[emiliocuestaf]

Adds a blackbox test that checks that:

• dds-pipe sets the original writer when the original writer is unknown
• dds-pipe keeps the original writer when it is known

This PR depends on eProsima/DDS-Pipe#163 and must be merged after it.

Maybe we can swap case 2 and case 3. In this way the expected value on the subscriber side will change between the three tested cases. Right now, case 1 and case 2 will generate the same value and it might occur that the value is not updated but the test does not report it.
