[PATCH v5 01/13] CI: set LOG_MSG as end-of-test marker consistently

[Marek Marczykowski-Górecki <marmarek@xxxxxxxxxxxxxxxxxxxxxx>]

Especially, do not set it to either empty string (not the same as
unset), nor to a message found earlier in the test execution. This
change will allow more consistent waiting for test end regardless of its
result.

Note for dom0less tests - waiting for dom0 prompt is not the right thing
to do, as the actual test is executed in domU, and those are started
asynchronously.
