cve-check: Consider CVE that affects versions with less than operator
In the NVD json CVE feed, affected versions can be strictly matched to a
version, but they can also be matched with the operator '<='.
Add a new condition in the sqlite query to match affected versions that
are defined with the operator '<='. Then use LooseVersion to discard all
versions that are not relevant.
