[OE-core] [PATCH V2 1/1] cve-check.bbclass: make warning contain CVE IDs

[Chen Qi]

When warning users about unpatched CVE, we'd better put CVE IDs into
the warning message, so that it would be more straight forward for the
user to know which CVEs are not patched.

So instead of:
  WARNING: gnutls-3.5.9-r0 do_cve_check: Found unpatched CVE, for more information check /path/to/workdir/cve/cve.log.
We should have:
  WARNING: gnutls-3.5.9-r0 do_cve_check: Found unpatched CVE (CVE-2017-7869), for more information check /path/to/workdir/cve/cve.log.
