X.509: Remove CRT policy parsing test 'bool len missing'
X.509: Remove CRT policy parsing test 'bool len missing'

Judging from its name, the purpose of the test

   TBSCertificate v3, ext CertificatePolicies tag, bool len missing

in test_suite_x509parse.data is to exercise the X.509 parsing stack's
behaviour when parsing a CertificatePolicy extension which lacks the
length field of the boolean 'Criticality' value.

However, the test fails at an earlier stage due to a mismatch of inner
and outer length of the explicit ASN.1 extensions structure.

Since we already have tests exercising

- mismatch of inner and outer length in the extensions structure, namely
  'X509 CRT ASN1 (TBS, inv v3Ext, inner tag invalid)'
- missing length of the 'Criticality' field in an extension, namely
  'X509 CRT ASN1 (TBS, inv v3Ext, critical length missing)'

and since for both tests there's no relevance to the use of the
policy extension OID, the test

  'TBSCertificate v3, ext CertificatePolicies tag, bool len missing'

can be dropped.
