Fix a race condition between autotestd and autotestd_monitor. If for
some reason the monitor starts up faster than autotestd, it can grab
the exit_code file before it exists (or theoretically it could lock it
after autotestd creates it but before it locks it).
To resolve this, have autotestd touch a "started" file after it creates
and locks the exit_code file, and have autotestd_monitor perform a
thirty second wait for it to exist before going ahead and trying to
grab the log files. In practice a wait of a couple of seconds is
sufficient to avoid the race.
Risk: Low
Visibility: Fixes a race condition between autotestd and
autotestd_monitor during client startup.
