Disable temporarily unsupported tests on Windows

Due to the changes introduced by the Automake migration, system tests
requiring Python (chain, pipelined, qmin, tcp), dynamic loading of
shared objects (dlzexternal, dyndb, filter-aaaa), or LMDB (nzd2nzf)
currently do not work on Windows.  Temporarily disable them on that
platform by moving them from the PARALLEL_COMMON list to the
PARALLEL_UNIX list until the situation is rectified.
