urara: Fix CBFS header definitions

Urara CBFS header configuration is broken. CBFS header needs to be
right above the bootblock, and the CBFS data - 0x100 bytes above, to
allow room for proper CBFS wrapper structures.

Ideally only the header offset should be specified (and even that
could be derived from the bootblock size). But this is a more generic
problem to be addressed with different architectures' image layout
requirements in mind.

BRANCH=none
BUG=chrome-os-partner:31438
TEST=coreboot image passes the integrity check now (it was failing
     before because CBGS header was overlaying the bootblock)
