cve-check: backport rewrite from master

As detailed at [1] the XML feeds provided by NIST are being discontinued on
October 9th 2019.  As cve-check-tool uses these feeds, cve-check.bbclass will be
inoperable after this date.

To ensure that cve-check continues working, backport the following commits from
master to move away from the unmaintained cve-check-tool to our own Python code
that fetches the JSON:

546d14135c5 cve-update-db: New recipe to update CVE database

-Subject: [PATCH] update: Compare computed vs expected sha256 digit string
- ignoring case
-
-We produce sha256 digest string using %x snprintf()
-qualifier for each byte of digest which uses alphabetic
-characters from "a" to "f" in lower case to represent
-integer values from 10 to 15.
-
-Previously all of the NVD META files supply sha256
-digest string for corresponding XML file in lower case.
-
-However due to some reason this changed recently to
-provide digest digits in upper case causing fetched
-data consistency checks to fail. This prevents database
-from being updated periodically.
-
-While commit c4f6e94 (update: Do not treat sha256 failure
-as fatal if requested) adds useful option to skip
-digest validation at all and thus provides workaround for
-this situation, it might be unacceptable for some
-deployments where we need to ensure that downloaded
-data is consistent before start parsing it and update
-SQLite database.
-
-Use strcasecmp() to compare two digest strings case
-insensitively and addressing this case.
