cve-check: CPE version '-' as all version
CPE version could be '-' to mean no version info. Current cve_check treat it as not valid and does not report these CVE but some of these could be a valid vulnerabilities. Since non-valid CVE can be whitelisted, so treat '-' as all version and report all these CVE to capture possible vulnerabilities. Non-valid CVE to be whitelisted separately.
