chromeos: Move files in //ash/common/system/chromeos to //ash/system

Ash only compiles on chromeos so there's no need for special /chromeos
subdirectories. We're also getting rid of //ash/common, so just move
everything into //ash/system.

Mechanical file moves:
* //ash/system/chromeos -> //ash/system
* //ash/common/system/chromeos -> //ash/system

Also fix some bad include guards.

This is a mechnical move with tools/git/mass-rename.py. No behavior
changes.
