* Append the yavta recipe found in:
meta-openembedded/meta-oe/recipes-multimedia/v4l2apps
to update it to the latest sources and update the applied
patch to work with those sources.
* This brings this recipe into line with mainline commit
bbc32a09b2b6a16d72331026d044eb4bfe17a4c5 and this bbappend
can be removed once meta-arago moves to the 1.7 release of
the Yocto project.
