Add new hardware_MemoryIntegrity test / refactor related test
This test call hardware_StorageFio to write data once to the ramfs
then idle/suspend for an hour before verify the data integrity.
Also refactor hardware_RamFio and hardware_Memtester to share
the existing code.
BUG=chromium:357856
TEST=Tested in peach_pit. Test passed.
