report: report unknown/-1 for binary fields with unknown value

Also respect --binary arg and/or report/binary_values_as_numeric
when displaying unknown values. If textual form is used, use "unknown",
if numeric value is used, use "-1" (which we already use to denote
unknown numeric values in other reports like lv_kernel_major and
lv_kernel_minor).
