common: don't follow reparse points in the Windows recursive file walk SysFileFindFiles recurses into every entry carrying FILE_ATTRIBUTE_DIRECTORY, which on Windows includes directory symlinks and junctions. A junction pointing at one of its own ancestors makes the walk recurse until the stack runs out. The Linux implementation already guards against this: it uses lstat rather than stat specifically so a symlink is never followed into a cycle. Skip reparse-point entries on Windows for the same reason. Co-authored-by: nmzik <Nmzik@mail.ru>
