security/vboot: Split fwid.region build target

Add the ability to specify the fwid version via a file instead of
via config. This makes it so when doing an incremental build all
objects are not invalidated when bumping the fwid.

The coreboot ebuild will create this file to pass the latest version.

BUG=b:112267918
TEST=ran dmidecide -t 0 and verified version was present
