Implement powerwash on Android.
Powerwash, the name for the equivalent of a factory reset or /data wipe,
can be triggered in Android by writing the desired command to the
recovery command file and rebooting into recovery.
This patch moves the powerwash scheduling/canceling logic to the
HardwareInterface and implements it on Android.
Bug: 28700985
TEST=Called update_engine_client passing POWERWASH=1, BCB is stored up
to offset 832.
