Oval data contains invalid `test_ref` which points nowhere

[yavor-atanasov]

Both the el8 and el9 ovals contain one invalid test_ref which points nowhere for defintion id oval:org.rockylinux.rlsa:def:20233661 (title RLSA-2023:3661: texlive security update (Important)).

The el9 oval data contains this invalid test for that definition:

  <criteria operator="OR">
    <criterion comment="Rocky Linux 8 must be installed"
      test_ref="oval:org.rockylinux.rlsa:tst:unk"/>
  </criteria>

Reciprocally, the el8 data contains this invalid:

  <criteria operator="OR">
    <criterion comment="Rocky Linux 9 must be installed"
      test_ref="oval:org.rockylinux.rlsa:tst:unk"/>
  </criteria>

The Red Hat ovals do not contain such a criteria for the same definition.

This is the area of the code where that invalid unk test reference is being injected:

oval/oval/transform.py

Lines 425 to 429 in 8f63e83

	tid = "unk"
	for test in tests :
	if test[ 'comment' ] == criteria[ 'comment' ] :
	tid = test[ 'id' ]
	break

I've not looked into that code in great detail, but it looks like instead of injecting an invalid test, the criteria should be skipped altogether.
