Cygwin: symlinks: Allow traversing WSL symlinks
Unfortunately Windows doesn't understand WSL symlinks,
despite being a really easy job. NT functions trying
to access paths traversing WSL symlinks return the status
code STATUS_IO_REPARSE_TAG_NOT_HANDLED. Handle this
status code same as STATUS_OBJECT_PATH_NOT_FOUND in
symlink_info::check to align behaviour to traversing
paths with other non-NTFS type symlinks.
