[PULL 13/36] tests/functional: Add a test for the arm microbit machine

[Peter Maydell]

From: Thomas Huth <thuth@redhat.com>

We don't have any functional tests for this machine yet, thus let's
add a test with a MicroPython binary that is available online
(thanks to Joel Stanley for providing it, see:
 https://www.mail-archive.com/qemu-devel@nongnu.org/msg606064.html ).
