tests/boot_linux_console: Add a SLOW test booting Ubuntu on OrangePi PC

This test boots Ubuntu Bionic on a OrangePi PC board.

As it requires 1GB of storage, and is slow, this test is disabled
on automatic CI testing.

It is useful for workstation testing. Currently Avocado timeouts too
quickly, so we can't run userland commands.

The kernel image and DeviceTree blob are built by the Armbian
project (based on Debian):
https://www.armbian.com/orange-pi-pc/

The Ubuntu image is downloaded from:
https://dl.armbian.com/orangepipc/Bionic_current

This test can be run using:

    avocado --show=app,console run -t machine:orangepi-pc \
