tests: Process VM stdout output in full lines

Browse source 
Merge partial lines together before processing them in parallel-vm.py.
This avoids issues in cases where the stdout read gets split into pieces
that do not include the full READY/PASS/FAIL/SKIP information. In
addition, strip unnecessary whitespace (mainly, '\r') from the log
lines.
