pe: read_header(): allow skipping SecDir content validation

When we're parsing the PE header of shim itself from the Loaded Image
object, the signatures aren't present, but the Certificate Table entry
in the Data Directory has not been cleared, so it'll fail verification.

We know when we're doing that, so this patch makes that test optional.
