audit: Fix CVE_PRODUCT

Fix "audit" set in CVE_PRODUCT to "linux:audit" to detect only vulnerabilities where the vendor is "linux".

Currently, CVE_PRODUCT also detects vulnerabilities where the vendor is "visionsoft",
which are unrelated to the "audit" in this recipe.
https://www.opencve.io/cve?vendor=visionsoft&product=audit

In addition, all the vulnerabilities currently detected in "audit" have the vendor of "visionsoft" or "linux".
Therefore, fix "audit" set in CVE_PRODUCT to "linux:audit".
