check-code: drop the rules for adding (glob) for Windows paths

I'll probably resurrect at least some of these as replacement patterns to switch
'\' to '/' when creating tests at some point.  But since this subset of globs
isn't needed anymore after dfae14354660, and the rules are blocking the glob
removal, just drop them for now.  It probably isn't worth turning them into
checks for unnecessary globs being present.
