cve-check: CPE version '-' as all version

Browse Source 
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.
