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.
