bmc_update.py: Call fw_setenv twice for PrepareForUpdate
Support for u-boot redundant environment variables was
added where u-boot alternates writing to each environment
every time an variable is written. But initramfs doesn't
know which environment is active so it always reads from
the same one. Therefore need to twice set the
environments that initramfs reads so that they're written
to both environments and initramfs can read it.
