Temporarily disable the "legacy" test on Windows

The current issues with the way dig handles TCP "connection refused"
errors cause the "legacy" system test to consistently fail on Windows
due to the expected strings not being present in dig output.
Temporarily disable the "legacy" system test on Windows by moving it
from the PARALLEL_COMMON list to the PARALLEL_UNIX list until the
situation is rectified.
