Add recipe for yamllint. There is an upcoming change in u-boot where
the binman tool is now configured to call yamllint to verify the configs
during compile time.
There was a previous patch a year ago from Trevor Woerner that never
made it into oe-core. This patch is a reworking of his patch but
pointing to a newer version.
