[PATCH] test-runner: make --log take a required argument

[James Prestwood <prestwoj@gmail.com>]

[-- Attachment #1: Type: text/plain, Size: 1814 bytes --]

This was a mistake in the original implementation. Since test-runner
is always run from the tools directory using --log with no directory
specified would result in many log files being put into the iwd tree.

Instead we can make --log take a required argument so its more
obvious where all the logs are going to go.
