[meta-freescale] [meta-fsl-arm][PATCH v2] gpu-viv-bin-mx6q: Add missing libffi dependency

[Jacob Kroon]

Running

  readelf --dynamic libgc_wayland_protocol.so | grep NEEDED

shows that the library has a runtime dependency on libffi. Same thing
applies to libwayland-viv.so.

Add libffi to DEPENDS for wayland builds, so that packaging can properly
detect the runtime dependency. For non-wayland builds, skip packaging
the files, so that they don't cause unexpected changes in buildhistory.
