cve-check: fix malformed cve status description with : characters

When CPE is not provided and character ":" is in cve status description,
current code takes only last part of split function.
This works only if there is no ":" in description, otherwise it drops
the other split parts.

Do a new split of the original string to take the whole description unchanged.
This fixes following entries from world build of poky+meta-oe+meta-python:
