wmlscope: import glob for Windows shell

The Windows cmd shell will not expand a globbed argument by default, in
fact it will make the argument invalid. Importing and utilizing the glob
module is needed for x-platform.

Globbing is especially important for breaking up the subtree, so wmlscope
doesn't give off "more than one resource/definition is visible here"
errors.
