[OE-core] [PATCH] Create class to test for unsatisfied RRECOMMENDS

[Jose Alarcon]

The do_rootfs log contains a number of unsatisfied package
recommendations. At the moment those are only visible when
reviewing the rootfs log.

This class adds an extra check to surface any unsatisfied
recommendation  as WARNINGS to the build output.
