tests/functional: Add a functional test for the collie board

Add a functional test for the collie board that uses the kernel and
rootfs provided by Guenter Roeck in the linux-test-downloads repo:
 https://github.com/groeck/linux-test-downloads/

This just boots Linux with a userspace that immediately reboots
the board, so we wait for the reboot log line.
