bundle_firmware: Add support for ifwi and sig2(cse_sign) blobs

For apollolake platform, two new blob types are required -- ifwi and
sig2(cse_sign). Both these blobs need to be simply copied from coreboot
image to final chromeos-bootimage using address and size from FMAP.

TEST=Tested by adding test ifwi and sig2 binaries to coreboot.rom
"emerge-reef chromeos-bootimage" generates bootimage with test ifwi and
sig2 binaries copied from coreboot.rom.
