installer: Return correct device nodes for NAND devs

On NAND device, rootfs, kernel, and other partitions have different
device names such as /dev/ubiX_0, /dev/mtdX, /dev/ubiblockX_0. This CL
changes utility functions such as GetBlockDevFromPartitionDev,
GetPartitionFromPartitionDev to return appropriate values for these
special device nodes.
