Fix "wait for log socket" in start.sh

The code in docker/base/start.sh that waits for the log socket does
not work because it includes a bad "space" character after "-S".

This patch changes that character to a real "space" character. It
also sets the SKIP_LOG_SETUP envvar for the Heka container.

TrivialFix
