[SeaBIOS] [PATCHv2] coreboot: Try to auto-detect if the CBFS anchor pointer is a relative pointer

I guess this heuristic should be very unlikely to fail with the
current cbfstool implementation, so I'd be fine with it (at least as
long as SeaBIOS is x86-only... non-x86 CBFS put the header close to
the start address instead).

Still, is anyone except Chrome OS actually using CONFIG_CBFS_LOCATION
and absolute offsets? Because we have completely switched over now,
and the absolute offset was hacked in as part of our SeaBIOS build
script which is now updated, so at least with our SDK you can't really
build a new SeaBIOS with the old-style absolute offset unless you
intentionally revert some stuff. If there's no other system out there
that still relies on absolute offsets, I'd suggest to just switch over
to the new relative style completely.
