[PATCH 4/7] test: sandbox: support testing with Labgrid

[Ahmad Fatoum]

From: Bastian Krause <bst at pengutronix.de>

It turns out there is already support in Labgrid to execute an
interactive console application and run tests against it.

Switch our test/sandbox/sandbox_defconfig.yaml to use this, so we can
eventually test sandbox in CI as well.

For proper operation, we require that labgrid doesn't buffer output
of the barebox sandbox process, which was recently fixed in [1].
