The answer is: it works with IPC::Run >= 0.98.  The version of IO::Pty
doesn't appear significant; it works at least back to 1.00 from early
2002.

IPC::Run 0.98 is relatively new (2018), so I don't think it'd fly
to make that our new minimum version across-the-board.  I recommend
just setting up this one test to SKIP if IPC::Run is too old.
