Collect storage information for chrome://system (with workaround fix for stout)
This script will run at startup and dump result in /var/log
for SSD device display smartctl and hdparm result
for eMMC device display various eMMC attribute e.g. CID, CSD
This script also include a workaround fix for stout machine.
(Run "smartctl -a" instead of "smartctl -x" on stout)
BUG=chromium:315380,chromium:328587
TEST=Tested in link, pit, stout
Reboot, verified that /var/log/storage_info show meaningful
result and SSD does not crash on stout.
