static layout: support factory reset

Implement factory reset for static flash layout, that starts
obmc-flash-bmc-setenv to set factory-reset u-boot env and let
init to do the cleanup.

Tested: Invoke factory reset on /xyz/openbmc_project/software and verify
        everything in rwfs is deleted, and after reboot, the BMC acts
        like a fresh new one.
