[oe] [meta-oe][PATCH V2] add CUnit test suite

[Gary S. Robertson]

Mike Holmes has asked me to resubmit this patch on his behalf, as other
duties have currently preempted his efforts to pursue acceptance of this
new recipe in OE.

A new patch file was added which sets the path configuration variables
to place documentation and headers in locations consistent with the
OE filesystem layout.

Looking in the ${WORKDIR}/*destdir and ${WORKDIR}/deploy-ipks subdirectories
after performing the recipe build, it appears that everything is being placed
into the appropriate locations.

We believe this version of the recipe addresses the concerns
raised in the email exchanges regarding the initial recipe submission,
and hope you will now find it acceptable.
