harness: add imx8x_local machine and some start for rackmount imx8x

Add a new machine imx8x_local, which assumes there is one imx8x attached
to your local machine. Now you can do:
./tools/harness/scalebench.py -m imx8x_local --debug -e build
-t memtest . build/results

scalebench: add option to produce junit xml output

This commit adds a new option (-x, --xml) to scalebench.py. This option can be
used to produce a XML file that can be parsed by Jenkins (and other software
that can parse JUnit test result reports) in order to provide more information
about the test run.

Webserver working for small websites

Harness test creates a file called bootlog.txt containing only Barrelfish console output.

Useful because the BIOS output usually comes with some weird
characters that can mess up your editor.

PEP-8 Autoformat for harness.py.

Initial version of public stable barrelfish repository.
