Correctly handle the lack of valid dm config parameters in the kernel
command line (dm="..."). In particular, skip trying to perform a rootfs
hash update for that kernel partition.
This change has the side effect of properly signing new recovery images
with the in-flight changes recovery install changes being done as part of
crosbug.com/22530.
Also fix verification of recovery images to consider both kernel partitions
for determing the hash to compare the calculated value against.
Finally, remove dd's verbose output while signing the firmware.

TEST=manually re-signed new (Alex) and old (Lumpy) recovery image. Verified
that recovery install works.
