charset="utf-8" Add a test for file migration using fdset. The passing of fds is more complex than using a file path. This is also the scenario where it's most important we ensure that the initial migration stream offset is respected because the fdset interface is the one used by the management layer when providing a non empty migration file. Note that fd passing is not available on Windows, so anything that uses add-fd needs to exclude that platform.
