oeqa: Clean up logger handling

The logger handling in oeqa was confused at best. This patch:

a) Passes in a logger through various qemu runner pieces
b) Uses that logger consistently in the code
c) Creates a logger for QemuRunner outside the bitbake namespace
   meaning we don't conflict with the tinfoil logging changes

The result of this is more consistency. For runtime tests in testimage,
the logs always contain the debug info, nothing is shwon on the console.
For the oe-selftests, logs are intercepted and only shown if the test
fails.
