rules: add mtd/by-name symlinks

Add persistent symlinks for MTD devices like SPI-NOR flash, based on the
partition names specified on the cmdline, in a Device Tree, or by other
MTD partitioning parser drivers. Using the persistent name can be
preferable to using the numbered /dev/mtdX device, as the latter can
change depending on probe order or when partitioning has changed.
