[PATCH] oeqa/qemurunner: Add extra logging when console doesn't appear

[Richard Purdie]

If the console doesn't appear, breifly sleep and try an extra read. This
is a useful debugging trick which we may as well preserve in the code. We're
already failing at this point so extra data is useful.

This means if we perturb things on the other port, we may gain useful logging
insight.
