[PATCH] automation: fix race condition in adl-suspend test

["Marek Marczykowski-Górecki" <marmarek@invisiblethingslab.com>]

If system suspends too quickly, the message for the test controller to
wake up the system may be not sent to the console before suspending.
This will cause the test to timeout.

Fix this by waiting a bit after printing the message. The test
controller then resumes the system 30s after the message, so as long as
the delay + suspending takes less time it is okay.

This is consistent with the observation that sync_console "fixes" the
issue.
