Archives listed as not requiring a binary lowpath, use lowpath type empty.

Archives CTR NAND, NAND RO Write FS, TWL NAND, NAND W FS, and CARD SPI FS require the corresponding process exheader access control mount flag to be set, in the exheader for any of the currently running ARM11 processes, for FSPXI. The access rights checked by FS module for archive mounting with fs:USER, are stored in the process' exheader accessinfo.
