vboot/vboot_kernel: update keyblock flag mismatch logic
A keyblock flag mismatch should cause keyblock verification to
fail regardless of whether a valid keyblock is required (i.e.
self-signed keyblock case).
This CL is part of a series to merge vboot1 and vboot2.0
kernel verification code; see b/181739551.
