send-to-lava: add support for publishing log files

For each test, send-to-lava will look into a results directory for files
named ${test}.log. If that file is found, then its contents will be
pushed to lava as the log snippet corresponding to that test.

The result directory can be passed as the second command line argument.
If omitted, the same directory as the results file will be used.
