tests/boot_linux_console: Test booting NetBSD via U-Boot on OrangePi PC

This test boots U-Boot then NetBSD (stored on a SD card) on
a OrangePi PC board.

As it requires ~1.3GB of storage, it is disabled by default.

U-Boot is built by the Debian project [1], and the SD card image
is provided by the NetBSD organization [2].

Once the compressed SD card image is downloaded (304MB) and
extracted, this test is fast:

Note, this test only took ~65 seconds to run on Travis-CI, see: [3].

This test is based on a description from Niek Linnenbank from [4].
