Add YoctoScannerParser

Yocto project support CVE security vulnerabilities using cve-check in the specific
image or target you are building, add the following setting to your configuration:

INHERIT += "cve-check"

status of each CVE: Patched, Unpatched or Ignored

The scanner look only for Unpatched package and calculate the severity using
the score_v2 or score_v3
