[RFC PATCH] tests/qtest: pass stdout/stderr down to subtests

["Alex Bennée" <alex.bennee@linaro.org>]

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.

While we are at it remove the g_test_verbose() check so we always show
how the QEMU is run.
