installer: select the fw_env config the way ffboot does

Browse Source 
Newer factory firmware's generic /etc/fw_env.config points at the
wrong device; its per-device /etc/fw_env_mmcblk2.config is the correct
one for the eMMC environment. The read-back verify caught the failed
write and aborted before the flip, as designed.
