contrib: dut-console: Add .log extension to log file name

This makes it more convenient when uploading the logs on buganizer,
as the mime type gets detected automatically and the log can be
displayed immediately (instead of requiring to download it first).

log-X.log is a little bit redundant, but I find it useful to keep
the log- prefix for all these files.

BUG=none
TEST=dut-console, output file ends in .log.
