[NETSHELL] Register folder attributes as SFGAO_FOLDER, not SFGAO_CAND…

…ELETE (reactos#5880)

On Windows the Network connections folder uses a binary value
and someone forgot about Little Endian when converting it to a DWORD.

Addendum to 7eb3fcf (r66485). CORE-9276

This issue has not been very visible because of bugs in CRegFolderEnum.
