tests: Make sure test output has \r\n line-ends when running on Windows

stinos · pfalcon · commit 24b03561bdc8 · 2015-10-31T14:11:19.000+03:00
This is the case already when using just subprocess.check_output, but in
the special cases (cmdline, meminfo, ...) the carriage return gets lost
during output processing so restore it in the end.
This fixes the micropython/meminfo.py test on Windows.
