run-tests: option for enabling automatic path matching on windows

run-tests.py will be even more strict than before. It will also fail on
path which do not need (glob). And it will write the expected output (with
glob appended or removed).
The option --winpathwarn enables automatic matching and only writes warning
messages for lines with missing glob.
With this change, users who can run the test-suite on windows can automatically
fix the output.
