obmc-flash-bmc: Mount alt rwfs

Mount the rwfs of the alt-bmc chip if present when the BMC
boots up to be able to synchronize (backup files) from the
BMC rwfs to the alt one, for the case when a chip switch
occurs then the persistent data is available on the alt chip.

Create a persist/etc directory to backup the /etc files to
it since that's the overlay's upperdir for /etc.
