rules: Fix by-path of mmc RPMB partitions and don't blkid them
Linux 3.10+ exposes RPMB (Replay Protected Memory Block) partitions of MMC devices [1] ; trying to read them with blkid or other unspecific means will cause kernel buffer I/O errors and timeouts. So don't run blkid on these. Also ensure that /dev/disk/by-path creates proper symlinks and exposes the -rpmb partition separately, instead of letting the "normal" partition symlink point to the rpbm device (this is a race condition).
