efi_loader: image_loader: add a check against certificate type of authenticode

UEFI specification requires that we shall support three type of
certificates of authenticode in PE image:
  WIN_CERT_TYPE_EFI_GUID with the guid, EFI_CERT_TYPE_PCKS7_GUID
  WIN_CERT_TYPE_PKCS_SIGNED_DATA
  WIN_CERT_TYPE_EFI_PKCS1_15

As EDK2 does, we will support the first two that are pkcs7 SignedData.
