[PATCH v4 14/22] tests/qtest: pass stdout/stderr down to subtests

[Alex Bennée]

When trying to work out what the virtio-net-tests where doing it was
hard because the g_test_trap_subprocess redirects all output to
/dev/null. Lift this restriction by using the appropriate flags so you
can see something similar to what the vhost-user-blk tests show when
running.
