apr-util: Add CVE_PRODUCT to support product name

apr-util is tracked in NVD under apache:apr-util, while a smaller set
of newer CVEs also appears under apache:portable_runtime_utility.
Set CVE_PRODUCT accordingly so cve-check can cover both the historical
and current NVD product identities used for APR-util.
