yocto-check-layer: add ability to perform tests from a global bbclass

This is useful when needing to test layer's recipes, where this special
bbclass can define a global python function that gets called on each
recipe parsing during "bitbake -S none world" signature dump and be able
to fail layer's check accordingly.

First test being added is to detect recipes skipping "installed-vs-shipped"
QA check. As "installed-vs-shipped" is a packaging QA check, it happens very
late in the build process and failing it could mean some potential issues
with packaging, especially when recipe uses BBCLASSEXTEND="nativesdk" and
resulting package is used in an SDK.

In OE-Core failing this QA check leads to an error, but other layers can
suppress it or change it to a warning. Detecting weird packaging problems
with SDKs is quite difficult and time consuming. Also, waiting for the
actual "installed-vs-shipped" packaging QA check to fail means that all
recipes in the layer under test have to run through all standard tasks in
the build chain, equivalent to a multi-hour world-build.

Hence yocto-check-layer takes a shortcut and only detects a mere attempt
at skipping "installed-vs-shipped" QA check in the INSANE_SKIP list during
initial parsing when dumping the signature information for the layer.
