cve-check: allow comparison of Vendor as well as Product
Some product names are too vague to be searched without also matching the
vendor, for example Flex could be the parser compiler we ship, or Adobe Flex, or
Apache Flex, or IBM Flex.
If entries in CVE_PRODUCT contain a colon then split it as vendor:product to improve the search.
Also don't use .format() to construct SQL as that can lead to security
issues. Instead, use ? placeholders and lets sqlite3 handle the escaping.
