fwlib: Map architecture armv7 to arm

In coreboot the architecture for our ARM platforms
is armv7. In order to have vboot_reference pick up the
right build parameters, map armv7 to arm.

TEST=lots more changes on coreboot needed for a reasonable
     test. Right now coreboot compiles fine with ramstage
     verification and this patch.
