Add initial capability to check CVEs for recipes

From: Mariano Lopez <[email protected]>

This series add the cve-check-tool recipe, a tool used to identify potentially vulnerable software through version matching. It will check if a vulnerability has been addressed by a patch.

Also add the new cve-check class that will add a task for all recipes to check for CVEs using cve-check-tool. This tool can be used by recipe, mage (will generate an image report in deploy dir), and with "world" and "universe"

To run it just inherit the class and enter:

bitbake -c cve_check <recipe>

Changes in v2:

- Set the explicit dependency of cve-check-tool-native:do_populate_cve_db in the cve-check class
- Squashed patch 2 into patch 1

Changes in v3:

- Support for python3
- Add check for BB_NO_NETWORK

Changes in v4:

- Support for GCC 6 adding -Wno-error=pedantic to CFLAGS
- Support for musl thanks to patch from Khem
- Tweaks when building the the CVE database
