bmc_update: save runtime modified u-boot environment

Copy the version saved by our initfs and pointed to by our fw_setenv
tools via /etc/fw_setenv.  Do this copy by default.

The /etc/fw_env.cnf config file points to /run/fw_env in our systems.

The bmc_update object was copying /dev/mtd2.  That could be very
system specific, and it misses any changes made from elsewhere
in the system.

This variable causes the u-boot environment to be written back
after writing the whole image.  This will save the ethernet mac
which for systems which don't store it elsewhere.
